 ### setActiveItemKey
 
-This function allows you to set a new active item key dynamically from within your component or from other components that consume the `useSideMenu` composable. It accepts a string that represents the key of the item you want to set as active. This value will be assigned to the `activeItemKey` ref.

 const {activeItemKey, setActiveItemKey} = useSideMenu(items, {
