A CloseOnClickEnum expression that determines the way the hosting menu is closed
when the user clicks the item.
You can specify a different way of closing the current item by specifying a
different value for Item's CloseOnClick property. For instance, you can specify the Item's CloseOnClick property on
exCloseOnClickOutside, for items of button type, so the hosting menu won't be
closed when the user clicks the button, and so the user can click multiple
times the item without closing the menu. The ShowAsButton
property indicates whether the item should look as a button. The ShowLocalPopup
property specifies whether the item's popup is shown as local. Clicking any item inside a local popup makes the popup itself to close including all its descendent sub-menus, without closing any ascendant sub-menus.
