Use the SubMenuStyle class to represent the style of a submenu in the Menu control. A submenu can be displayed within either a static menu or a dynamic menu. A static menu is always visible on a Menu control, whereas a dynamic menu is displayed only when the user positions the mouse pointer over a parent menu item that contains a dynamic submenu. You can specify different style characteristics (such as font size and color) for the submenus within a static menu and a dynamic menu by using the properties in the following table.

Submenu item style property

Description

DynamicMenuStyle

The style settings for a submenu within a dynamic menu.

StaticMenuStyle

The style settings for a submenu within a static menu.

The SubMenuStyle class inherits most of its members from the Style class. It extends the Style class by providing properties that control the amount of space around a menu item's text. Use the HorizontalPadding property to control the amount of space to the left and right of the menu item's text. Similarly, the VerticalPadding property controls the amount of space above and below the menu item's text.

For more information on the inherited style settings, see Style.

NoteNote

Set the z-index of HTML objects that are associated with a submenu by setting the CssClass property of the submenu style. The z-index attribute defines the stacking order of rendered HTML objects. By default, dynamic menu items will appear above any HTML object that has the default z-index (0).

The following example demonstrates how to specify a custom style for a submenu within a dynamic menu.
