MenuItem.Selectable Property
Gets or sets a value that indicates whether the MenuItem object can be selected, or is "clickable."
Assembly: System.Web (in System.Web.dll)
When this property is set to false on a menu item, no action occurs when the menu item is clicked (selected). The pop-out image indicating child menu items for the menu item, if one exists, is still shown and available.
If you do not want any child menu items to appear for a menu item, set the Enabled property to false.
Selectable applies only to menu items that can be selected, in the sense that clicking a menu item posts back and sets that item in the selected state. Note that a menu item that cannot be selected is still formatted as a link. This is for accessibility reasons, so that the menu item can cause an action to occur. Also, a menu item, even if it cannot be selected, may have child menu items that can be selected or that need to be displayed.
If you want to prevent a user from clicking a menu item, do one of the following:
Do not set NavigateUrl and set Selectable to false.
Set the menu item's Enabled property to false.
The following example demonstrates how a menu item with the Selectable property set to false appears and functions in a menu.
