+### contextmenus.lua
+
+These functions provide a unified way to interact with different context menu systems, such as OX and WarMenu, depending on what's available on the server.
+
+- **openMenu(Menu, data)**
+
+  - Opens a context menu using the preferred menu system.
+  - Automatically selects between supported systems like OX or WarMenu based on availability.
+  - The `Menu` parameter should be a list of menu entries, and the `data` parameter can be used to set headers, subtexts, and actions like `onBack`, `onExit`, and `canClose`.
+  - **Example:**
+    ```lua
+    openMenu({
+        { header = "Option 1", txt = "Description 1", onSelect = function() print("Option 1 selected") end },
+        { header = "Option 2", txt = "Description 2", onSelect = function() print("Option 2 selected") end },
+    }, {
+        header = "Main Menu",
+        headertxt = "Select an option",
+        onBack = function() print("Return selected") end,
+        onExit = function() print("Menu closed") end,
+        canClose = true,
+    })
+    ```
+
+- **isOx()**
+
+  - Checks whether the OX context menu system is available on the server.
+  - Allows to do specific things if ox_lib menu is in use
+  - **Example:**
+    ```lua
+    if isOx() then
+        print("OX Context Menu is available")
+    end
+    ```
+
+- **isWarMenuOpen()**
+
+  - Returns whether WarMenu is currently open.
+  - Useful to prevent opening a new menu if one is already active.
+  - **Example:**
+    ```lua
+    if not isWarMenuOpen() then
+        openMenu("main_menu", menuData)
+    end
+    ```
+  - Returns whether the WarMenu is currently open.
