ASP.net on Mouse click submenu items should appear

Question

In my web application ,ASP. Net Menu item control pops up when using mouse-over on desktop but touchscreen could be a problem. If user uses mouse over the ASP.net Main menu ,the main menu and submenus pops up in desktop after using disappearafter =999 and selectable =true in menu control. when I tap the main menu using touch screen devices, submenu disappears before selecting.

How to write mouse click instead of mouse over in asp.net menu item and will it work for both desktop/touch screen devices. Any help is appreciated.
