下列程式碼範例會顯示包含兩個自訂的布林值屬性、 ParentItemIsVisible和EnableItem1，可讓您控制這些功能表項目時是可見並已啟用覆寫的CreateWebPartMenu 。它也會假設此方法會包含名為EventHandlerForItem1事件處理常式的網頁組件類別的一部分。

Public Overrides Sub CreateWebPartMenu()
    ' Declare variables for menu items.
    Dim ParentItem As MenuItem
    Dim Item1 As MenuItem

    ' One parent item, and two submenu items.
    ' Create the parent item.
    ParentItem = New MenuItem("ParentItem", "", "ParentItemID")
    
    ' Create a submenu item with a server event on click.
    Item1 = New MenuItem("Item1", "Item1ID", New EventHandler(AddressOf EventHandlerForItem1))
