Sample example

public override void CreateWebPartMenu()
MenuItem ParentItem, Item1, Item2;

//first we create three menu items 
//one as a 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(EventHandlerForItem1));

//create a submenu item with a client event on click 
Item2 = new MenuItem("Item2", "javascript:alert('Item2 was clicked');", "Item2ID");
// We then add the submenu items to the parent item. 


// We then decide that we'd like to add the parent item after the 
// "Edit Web Part Properties" item in the menu. 
// First we find the index of the "Edit" item 
int EditIndex =

// Then we insert the parent item after the "Edit" item 
this.WebPartMenu.MenuItems.Insert(EditIndex + 1, ParentItem);

// Make sure the parent item has a separator above it 
ParentItem.BeginSection = true;

// Check a custom property to decide whether to display the parent menu 
if (this.CustomProperty1 == true)
ParentItem.Visible = true;
ParentItem.Visible = false;
// Check another custom property to decide which menu item to enable 
// within the parent item 
if (this.CustomProperty2 == true)
Item1.Enabled = true;
Item2.Enabled = false;
Item1.Enabled = false;
Item2.Enabled = true;
