**Start here:** Read [`CS2-SimpleAdmin_FunCommands/README.md`](./CS2-SimpleAdmin_FunCommands/README.md)
### Step 2: Create Your Module Structure
```
YourModule/
├── YourModule.csproj # Project file
├── YourModule.cs # Main plugin class
├── Commands.cs # Command handlers (optional)
├── Menus.cs # Menu creation (optional)
├── Config.cs # Configuration
└── lang/ # Translations
├── en.json
├── pl.json
└── ru.json
```
### Step 3: Minimal Working Example (NEW MenuContext API!)
```csharp
using CounterStrikeSharp.API.Core;
using CounterStrikeSharp.API.Core.Capabilities;
using CS2_SimpleAdminApi;
public class MyModule : BasePlugin
{
private ICS2_SimpleAdminApi? _api;
private readonly PluginCapability<ICS2_SimpleAdminApi> _pluginCapability = new("simpleadmin:api");
public override void OnAllPluginsLoaded(bool hotReload)
{
_api = _pluginCapability.Get();
if (_api == null)
{
Logger.LogError("CS2-SimpleAdmin API not found");
return;
}
// Register menus after API is ready
_api.OnSimpleAdminReady += RegisterMenus;
RegisterMenus(); // Fallback for hot reload
}
private void RegisterMenus()
{
if (_api == null) return;
// 1. Register a new category
// IMPORTANT: If your module has lang/ folder with translations, use YOUR module's Localizer!
// Example: _api.RegisterMenuCategory("mymodule", Localizer?["mymodule_category_name"] ?? "My Module", "@css/generic");
//
// This will use YOUR module's translations in server language.
// For modules without translations, you can use hard-coded text:
_api.RegisterMenuCategory("mymodule", "My Module", "@css/generic");
// 2. Register menu items in the category
// 🆕 NEW: Use MenuContext-aware overload (no duplication!)
// NOTE: Use YOUR module's Localizer if you have lang/ folder with translations:
// _api.RegisterMenu("mymodule", "action1", Localizer?["mymodule_menu_action1"] ?? "Action 1", CreateAction1Menu, "@css/generic");
_api.RegisterMenu("mymodule", "action1", "Action 1", CreateAction1Menu, "@css/generic");
_api.RegisterMenu("mymodule", "action2", "Action 2", CreateAction2Menu, "@css/kick");
}
// 🆕 NEW: Factory now receives MenuContext parameter
private object CreateAction1Menu(CCSPlayerController admin, MenuContext context)
{
// Create a menu with automatic back button
// Use context instead of repeating title and category!
var menu = _api!.CreateMenuWithBack(context, admin);
// Add menu options
_api.AddMenuOption(menu, "Option 1", player =>
{
player.PrintToChat("You selected Option 1");
});
_api.AddMenuOption(menu, "Option 2", player =>
{
player.PrintToChat("You selected Option 2");
});
return menu;
}
// 🆕 NEW: MenuContext eliminates duplication here too!
private object CreateAction2Menu(CCSPlayerController admin, MenuContext context)
{
// Use the built-in player selection menu with context
return _api!.CreateMenuWithPlayers(
context, // ← Contains title & category automatically!
admin,
player => player.IsValid && admin.CanTarget(player),
(adminPlayer, targetPlayer) =>
{
adminPlayer.PrintToChat($"You selected {targetPlayer.PlayerName}");
});
}
public override void Unload(bool hotReload)
{
if (_api == null) return;
// Clean up registered menus
_api.UnregisterMenu("mymodule", "action1");
_api.UnregisterMenu("mymodule", "action2");
_api.OnSimpleAdminReady -= RegisterMenus;
}
}
```

## 🎯 Menu Patterns
The FunCommands module demonstrates **3 essential menu patterns** you'll use in every module:
### Pattern 1: Simple Player Selection (NEW MenuContext API!)
**When to use:** Select a player and immediately execute an action
```csharp
// 🆕 NEW: Factory receives MenuContext - eliminates duplication!
private object CreateGodModeMenu(CCSPlayerController admin, MenuContext context)
{
return _api.CreateMenuWithPlayers(
context, // ← Contains title & category automatically!
admin, // Admin
player => player.IsValid && admin.CanTarget(player), // Filter
(adminPlayer, target) => // Action
{
// Execute action immediately
ToggleGodMode(target);
});
}
```
**Why MenuContext is better:**
-**Old way:** `"God Mode"` and `"yourmodule"` had to be typed twice (in RegisterMenu and CreateMenuWithPlayers)
-**New way:** Context contains both automatically - no duplication, no mistakes!
**See:** `CS2-SimpleAdmin_FunCommands/Menus.cs:44-51`
### Pattern 2: Nested Menu (Player → Value) - NEW MenuContext API!
**When to use:** Select a player, then select a value/option for that player
```csharp
// 🆕 NEW: Uses MenuContext to eliminate duplication
private object CreateSetHpMenu(CCSPlayerController admin, MenuContext context)
{
var menu = _api.CreateMenuWithBack(context, admin); // ← No more repeating title & category!
var players = _api.GetValidPlayers().Where(p => admin.CanTarget(p));
foreach (var player in players)
{
// AddSubMenu automatically adds back button to submenu
_api.AddSubMenu(menu, player.PlayerName,
p => CreateHpValueMenu(admin, player));
}
return menu;
}
// Example: Set HP menu (value selection)
// Note: Submenus don't receive context - they create dynamic titles
private object CreateHpValueMenu(CCSPlayerController admin, CCSPlayerController target)
{
var menu = _api.CreateMenuWithBack($"HP for {target.PlayerName}", "yourmodule", admin);
var values = new[] { 50, 100, 200, 500 };
foreach (var hp in values)
{
_api.AddMenuOption(menu, $"{hp} HP", _ =>
{
if (target.IsValid) // Always validate!
{
target.PlayerPawn.Value.Health = hp;
}
});
}
return menu;
}
```
**Benefits of MenuContext:**
- ✅ Change menu title in one place (RegisterMenu) and it updates everywhere
- ✅ Can't accidentally mistype category ID
- ✅ Access to permission and command name from context if needed
**See:** `CS2-SimpleAdmin_FunCommands/Menus.cs:163-178`
### Pattern 3: Nested Menu with Complex Data
**When to use:** Need to display more complex options (like weapons with icons, items with descriptions)
```csharp
// Example: Give Weapon menu
private object CreateGiveWeaponMenu(CCSPlayerController admin)
{
var menu = _api.CreateMenuWithBack("Give Weapon", "yourmodule", admin);
var players = _api.GetValidPlayers().Where(p => admin.CanTarget(p));
foreach (var player in players)
{
_api.AddSubMenu(menu, player.PlayerName,
p => CreateWeaponSelectionMenu(admin, player));
}
return menu;
}
private object CreateWeaponSelectionMenu(CCSPlayerController admin, CCSPlayerController target)
{
var menu = _api.CreateMenuWithBack($"Weapons for {target.PlayerName}", "yourmodule", admin);
// Use cached data for performance
foreach (var weapon in GetWeaponsCache())
{
_api.AddMenuOption(menu, weapon.Value.ToString(), _ =>
{
if (target.IsValid)
{
target.GiveNamedItem(weapon.Value);
}
});
}
return menu;
}
```
**See:** `CS2-SimpleAdmin_FunCommands/Menus.cs:67-109`
## 🆕 MenuContext API (New!)
### What is MenuContext?
`MenuContext` is a new feature that eliminates code duplication when creating menus. When you register a menu, you provide information like title, category, and permissions. Previously, you had to repeat this information in your menu factory method. Now, this information is automatically passed to your factory via `MenuContext`.
### MenuContext Properties
```csharp
public class MenuContext
{
public string CategoryId { get; } // e.g., "fun"
public string MenuId { get; } // e.g., "god"
public string MenuTitle { get; } // e.g., "God Mode"
public string? Permission { get; } // e.g., "@css/cheats"
public string? CommandName { get; } // e.g., "css_god"
}
```
### Before vs After Comparison
```csharp
// ❌ OLD API - Duplication everywhere
_api.RegisterMenu("fun", "god", "God Mode", CreateGodModeMenu, "@css/cheats");
private object CreateGodModeMenu(CCSPlayerController admin)
{
return _api.CreateMenuWithPlayers(
"God Mode", // ← Duplicated from RegisterMenu
"fun", // ← Duplicated from RegisterMenu
admin, filter, action);
}
// ✅ NEW API - No duplication!
_api.RegisterMenu("fun", "god", "God Mode", CreateGodModeMenu, "@css/cheats");
private object CreateGodModeMenu(CCSPlayerController admin, MenuContext context)
{
return _api.CreateMenuWithPlayers(
context, // ← Contains all info automatically!
admin, filter, action);
}
```
### When to Use MenuContext
| Menu Creation Method | Old Signature | New Signature (Recommended) |
|---------------------|---------------|----------------------------|
| `CreateMenuWithBack` | `(string title, string categoryId, ...)` | `(MenuContext context, ...)` |
| `CreateMenuWithPlayers` | `(string title, string categoryId, ...)` | `(MenuContext context, ...)` |
**Rule of thumb:** If you're creating a menu directly from a registered menu factory, use `MenuContext`. For dynamic submenus (e.g., player-specific menus), use the old API.
### Backward Compatibility
The old API still works! Both signatures are supported:
```csharp
// ✅ Old API - still works
_api.RegisterMenu("cat", "id", "Title",
(CCSPlayerController admin) => CreateOldStyleMenu(admin));
// ✅ New API - recommended
_api.RegisterMenu("cat", "id", "Title",
(CCSPlayerController admin, MenuContext ctx) => CreateNewStyleMenu(admin, ctx));
```
## 📋 API Methods Reference
### 1. Category Management
#### `RegisterMenuCategory(string categoryId, string categoryName, string permission = "@css/generic")`
Registers a new menu category that appears in the main admin menu.
**Parameters:**
- `categoryId` - Unique identifier for the category (e.g., "fun", "vip", "economy")
- `categoryName` - **TRANSLATION KEY** for the display name (e.g., "vip_category_name", NOT "VIP Features")
- `permission` - Required permission to see the category (default: "@css/generic")
**IMPORTANT FOR MODULES WITH TRANSLATIONS:**
- If your module has a `lang/` folder with translation files, use **YOUR module's Localizer**
- This will display menu names in the **server's language** (not per-player)
- For per-player localization, only **CS2-SimpleAdmin's built-in menus** support this currently
**Example:**
```csharp
// ✅ CORRECT: Module with translations uses its own Localizer
_api.RegisterMenuCategory("vip", Localizer?["vip_category_name"] ?? "VIP Features", "@css/vip");
// In YOUR module's lang/en.json: "vip_category_name": "VIP Features"
// In YOUR module's lang/pl.json: "vip_category_name": "Funkcje VIP"
// ✅ ALSO CORRECT: Module without translations uses hard-coded text
_api.RegisterMenuCategory("vip", "VIP Features", "@css/vip");
// ❌ INCORRECT: Using translation key without Localizer
_api.RegisterMenuCategory("vip", "vip_category_name", "@css/vip");
// This would display "vip_category_name" literally!
```
### 2. Menu Registration
#### `RegisterMenu(string categoryId, string menuId, string menuName, Func<CCSPlayerController, object> menuFactory, string? permission = null)`
Registers a menu item within a category.
**Parameters:**
- `categoryId` - The category to add this menu to
- `menuId` - Unique identifier for the menu
- `menuName` - Display name for the menu (use **your module's Localizer** if you have translations)
- `menuFactory` - Function that creates the menu when selected (receives admin player and MenuContext)
- `permission` - Optional permission required to see this menu item
**IMPORTANT FOR MODULES WITH TRANSLATIONS:**
- Use **your module's Localizer** if you have a `lang/` folder: `Localizer?["key"] ?? "Fallback"`
- This shows menu in **server language**, not per-player
- Per-player localization is only available for CS2-SimpleAdmin's built-in menus
**Example:**
```csharp
// ✅ CORRECT: Module with translations uses its own Localizer
_api.RegisterMenu("fun", "godmode", Localizer?["fun_menu_god"] ?? "God Mode", CreateGodModeMenu, "@css/cheats");
// In YOUR module's lang/en.json: "fun_menu_god": "God Mode"
// In YOUR module's lang/pl.json: "fun_menu_god": "Tryb Boga"
// ✅ ALSO CORRECT: Module without translations uses hard-coded text
_api.RegisterMenu("fun", "godmode", "God Mode", CreateGodModeMenu, "@css/cheats");
// ❌ INCORRECT: Using translation key without Localizer
_api.RegisterMenu("fun", "godmode", "fun_menu_god", CreateGodModeMenu, "@css/cheats");
// This would display "fun_menu_god" literally!
```
#### `UnregisterMenu(string categoryId, string menuId)`
Removes a menu item from a category.
**Example:**
```csharp
_api.UnregisterMenu("fun", "godmode");
```
### 3. Menu Creation
#### `CreateMenuWithBack(string title, string categoryId, CCSPlayerController player)`
#### `CreateMenuWithBack(MenuContext context, CCSPlayerController player)` 🆕 NEW!
Creates a menu with an automatic "Back" button that returns to the category menu.

- `player` - The admin player viewing the menu
**Returns:** `object` (MenuBuilder instance)
**Example (Old API):**
```csharp
var menu = _api.CreateMenuWithBack("Weapon Selection", "fun", admin);
```
**Example (New API - Recommended):**
```csharp
private object CreateWeaponMenu(CCSPlayerController admin, MenuContext context)
{
var menu = _api.CreateMenuWithBack(context, admin); // ← Uses context!
// ... add options
return menu;
}
```
#### `CreateMenuWithPlayers(string title, string categoryId, CCSPlayerController admin, Func<CCSPlayerController, bool> filter, Action<CCSPlayerController, CCSPlayerController> onSelect)`
#### `CreateMenuWithPlayers(MenuContext context, CCSPlayerController admin, Func<CCSPlayerController, bool> filter, Action<CCSPlayerController, CCSPlayerController> onSelect)` 🆕 NEW!
Creates a menu with a list of players, filtered and with automatic back button.
**Parameters (Old API):**

- `categoryId` - Category for back navigation
- `admin` - The admin player viewing the menu
- `filter` - Function to filter which players appear in the menu
- `onSelect` - Action to execute when a player is selected (receives admin and target)
**Parameters (New API - Recommended):**
- `context` - MenuContext containing title and category
- `admin` - The admin player viewing the menu
- `filter` - Function to filter which players appear in the menu
- `onSelect` - Action to execute when a player is selected (receives admin and target)
**Returns:** `object` (MenuBuilder instance)

```csharp
return _api.CreateMenuWithPlayers("Select Player to Kick", "admin", admin,
player => player.IsValid && admin.CanTarget(player),
(adminPlayer, targetPlayer) =>
{
// Kick the selected player
Server.ExecuteCommand($"css_kick {targetPlayer.UserId}");
});
```
**Example (New API - Recommended):**
```csharp
private object CreateKickMenu(CCSPlayerController admin, MenuContext context)
{
return _api.CreateMenuWithPlayers(context, admin,
player => player.IsValid && admin.CanTarget(player),
(adminPlayer, targetPlayer) =>
{
Server.ExecuteCommand($"css_kick {targetPlayer.UserId}");
});
}
```
### 4. Menu Manipulation
#### `AddMenuOption(object menu, string name, Action<CCSPlayerController> action, bool disabled = false, string? permission = null)`
Adds a clickable option to a menu.
**Parameters:**
- `menu` - The menu object (from CreateMenuWithBack)
- `name` - Display name of the option
- `action` - Action to execute when clicked (receives the player who clicked)
- `disabled` - Whether the option is disabled (grayed out)

}, permission: "@css/cheats");
```
#### `AddSubMenu(object menu, string name, Func<CCSPlayerController, object> subMenuFactory, bool disabled = false, string? permission = null)`
Adds a submenu option that opens another menu. **Automatically adds a back button to the submenu.**
**Parameters:**
- `menu` - The parent menu
- `name` - Display name of the submenu option
- `subMenuFactory` - Function that creates the submenu (receives the player)
- `disabled` - Whether the option is disabled
- `permission` - Optional permission required
**Example:**
```csharp
_api.AddSubMenu(menu, "Weapon Category", player =>
{
var weaponMenu = _api.CreateMenuWithBack("Weapons", "fun", player);
_api.AddMenuOption(weaponMenu, "AK-47", p => p.GiveNamedItem("weapon_ak47"));
_api.AddMenuOption(weaponMenu, "AWP", p => p.GiveNamedItem("weapon_awp"));
return weaponMenu;
});
```
#### `OpenMenu(object menu, CCSPlayerController player)`
Opens a menu for a specific player.
**Example:**
```csharp
var menu = _api.CreateMenuWithBack("Custom Menu", "fun", player);
_api.AddMenuOption(menu, "Test", p => p.PrintToChat("Test!"));
_api.OpenMenu(menu, player);
```
## Advanced Examples
### Nested Menus with Player Selection
```csharp
private object CreateGiveWeaponMenu(CCSPlayerController admin)
{
var menu = _api.CreateMenuWithBack("Give Weapon", "fun", admin);
var players = _api.GetValidPlayers()
.Where(p => p.PlayerPawn?.Value?.LifeState == (int)LifeState_t.LIFE_ALIVE && admin.CanTarget(p));
foreach (var player in players)
{
// Add submenu for each player - automatic back button will be added
_api.AddSubMenu(menu, player.PlayerName, p => CreateWeaponSelectionMenu(admin, player));
}
return menu;
}
private object CreateWeaponSelectionMenu(CCSPlayerController admin, CCSPlayerController target)
{
var weaponMenu = _api.CreateMenuWithBack($"Weapons for {target.PlayerName}", "fun", admin);
var weapons = new[] { "weapon_ak47", "weapon_m4a1", "weapon_awp", "weapon_deagle" };
foreach (var weapon in weapons)
{
_api.AddMenuOption(weaponMenu, weapon, _ =>
{
if (target.IsValid)
{
target.GiveNamedItem(weapon);
admin.PrintToChat($"Gave {weapon} to {target.PlayerName}");
}
});
}
return weaponMenu;
}
```
### Dynamic Menu with Value Selection
```csharp
private object CreateSetHpMenu(CCSPlayerController admin)
{
var menu = _api.CreateMenuWithBack("Set HP", "admin", admin);
var players = _api.GetValidPlayers().Where(p => admin.CanTarget(p));
foreach (var player in players)
{
_api.AddSubMenu(menu, player.PlayerName, p => CreateHpValueMenu(admin, player));
}
return menu;
}
private object CreateHpValueMenu(CCSPlayerController admin, CCSPlayerController target)
{
var hpMenu = _api.CreateMenuWithBack($"HP for {target.PlayerName}", "admin", admin);
var hpValues = new[] { 1, 50, 100, 200, 500, 1000 };
foreach (var hp in hpValues)
{
_api.AddMenuOption(hpMenu, $"{hp} HP", _ =>
{
if (target.IsValid && target.PlayerPawn?.Value != null)
{
target.PlayerPawn.Value.Health = hp;
admin.PrintToChat($"Set {target.PlayerName} HP to {hp}");
}
});
}
return hpMenu;
}
```
### Permission-Based Menu Options
```csharp
private object CreateAdminToolsMenu(CCSPlayerController admin)
{
var menu = _api.CreateMenuWithBack("Admin Tools", "admin", admin);
// Only root admins can see this
_api.AddMenuOption(menu, "Dangerous Action", player =>
{
player.PrintToChat("Executing dangerous action...");
}, permission: "@css/root");
// All admins can see this
_api.AddMenuOption(menu, "Safe Action", player =>
{
player.PrintToChat("Executing safe action...");
}, permission: "@css/generic");
return menu;
}
```
## Best Practices
1. **Use your module's Localizer for translations** 🌍
```csharp
// ✅ CORRECT: Module with translations uses its own Localizer
_api.RegisterMenuCategory("mymodule", Localizer?["mymodule_category"] ?? "My Module", "@css/generic");
_api.RegisterMenu("mymodule", "action", Localizer?["mymodule_menu_action"] ?? "My Action", CreateMenu, "@css/generic");
// ✅ ALSO CORRECT: Module without translations uses hard-coded text
_api.RegisterMenuCategory("mymodule", "My Module", "@css/generic");
_api.RegisterMenu("mymodule", "action", "My Action", CreateMenu, "@css/generic");
// ❌ WRONG: Using translation key without Localizer
_api.RegisterMenuCategory("mymodule", "mymodule_category", "@css/generic");
// This would display "mymodule_category" literally!
```
**✅ Per-player localization now available!**
- Both CS2-SimpleAdmin built-in menus AND module menus support per-player localization
- Each player sees menus in their own language based on their `css_lang` setting
- See "Advanced: Per-Player Localization for Modules" section below for implementation details
2. **Always check for API availability**
```csharp
if (_api == null) return;
```
3. **Validate player state before actions**
```csharp
if (target.IsValid && target.PlayerPawn?.Value != null)
{
// Safe to perform action
}
```
4. **Use descriptive category and menu IDs**
- Good: `"economy"`, `"vip_features"`, `"fun_commands"`
- Bad: `"cat1"`, `"menu"`, `"test"`
5. **Clean up on unload**
```csharp
public override void Unload(bool hotReload)
{
_api?.UnregisterMenu("mymodule", "mymenu");
_api.OnSimpleAdminReady -= RegisterMenus;
}
```
6. **Use appropriate permissions**
- `@css/generic` - All admins
- `@css/ban` - Admins who can ban
- `@css/kick` - Admins who can kick
- `@css/root` - Root admins only
- Custom permissions from your module
7. **Handle hot reload**
```csharp
_api.OnSimpleAdminReady += RegisterMenus;
RegisterMenus(); // Fallback for hot reload case
```
## Automatic Back Button
The menu system **automatically adds a "Back" button** to all submenus created with:
- `CreateMenuWithBack()` - Returns to the category menu
- `AddSubMenu()` - Returns to the parent menu
You don't need to manually add back buttons - the system handles navigation automatically!
## Getting Valid Players
Use the API helper method to get valid, connected players:
```csharp
var players = _api.GetValidPlayers();
// With filtering
var alivePlayers = _api.GetValidPlayers()
.Where(p => p.PlayerPawn?.Value?.LifeState == (int)LifeState_t.LIFE_ALIVE);
var targetablePlayers = _api.GetValidPlayers()
.Where(p => admin.CanTarget(p));
```
## Complete Module Example
See the `CS2-SimpleAdmin_FunCommands` module in the `Modules/` directory for a complete, production-ready example of:
- Category registration
- Multiple menu types
- Nested menus with automatic back buttons
- Player selection menus
- Permission-based access
- Proper cleanup on unload
## Troubleshooting
**Q: My category doesn't appear in the admin menu**
- Ensure you're calling `RegisterMenuCategory()` after the API is ready
- Check that the player has the required permission
- Verify the category has at least one menu registered with `RegisterMenu()`
**Q: Back button doesn't work**
- Make sure you're using `CreateMenuWithBack()` instead of creating menus manually
- The `categoryId` parameter must match the category you registered
- Use `AddSubMenu()` for nested menus - it handles back navigation automatically
**Q: Menu appears but is empty**
- Check that you're adding options with `AddMenuOption()` or `AddSubMenu()`
- Verify permission checks aren't filtering out all options
- Ensure player validation in filters isn't too restrictive
**Q: API is null in OnAllPluginsLoaded**
- Wait for the `OnSimpleAdminReady` event instead of immediate registration
- Make sure CS2-SimpleAdmin is loaded before your module
## Advanced: Per-Player Localization for Modules (✅ NOW AVAILABLE!)
**🆕 NEW:** Module menus now support **per-player localization** based on `css_lang`!
Both CS2-SimpleAdmin's built-in menus AND module menus can show in each player's configured language.
### How to Use Per-Player Localization in Your Module
**1. Register Category with Localizer:**
```csharp
// Pass translation KEY (not translated text) and module's Localizer
_api.RegisterMenuCategory(
"mymodule",
"mymodule_category_name", // Translation key from your lang/ folder
"@css/generic",
Localizer! // Your module's localizer
);
```
**2. Register Menus with Localizer:**
```csharp
_api.RegisterMenu(
"mymodule",
"action",
"mymodule_menu_action", // Translation key from your lang/ folder
CreateMenu,
"@css/generic", // Permission
"css_mycommand", // Command name for override (optional)
Localizer! // Your module's localizer
);
```
**How it works:**
1. Your module passes its `IStringLocalizer` and translation **key** (not translated text)
2. SimpleAdmin's `MenuManager` stores both the key and the localizer
3. When displaying menu to a player, MenuManager translates using:
```csharp
using (new WithTemporaryCulture(player.GetLanguage()))
{
localizedName = moduleLocalizer[translationKey];
}
```
4. Each player sees menus in their own language based on their `css_lang` setting!
**Complete Example:**
See `Modules/CS2-SimpleAdmin_FunCommands/` for a real implementation:
```csharp
// Register category with per-player localization
_api.RegisterMenuCategory("fun", "fun_category_name", "@css/generic", Localizer!);
// Register menu with per-player localization
_api.RegisterMenu("fun", "god", "fun_menu_god",
CreateGodModeMenu, "@css/cheats", "css_god", Localizer!);
```
**Without Per-Player Localization (backwards compatible):**
If you don't need per-player localization, the old API still works:
```csharp
// Hard-coded text (same for all players)
_api.RegisterMenuCategory("mymodule", "My Module", "@css/generic");
_api.RegisterMenu("mymodule", "action", "Do Action", CreateMenu, "@css/generic");
```
