Reagrding using FILTER in (MenuExample.css) CSS adapter classes for Menu control

Hello everyone,

Whenever I use filter: in any of the CSS calss for the MENU control using CSS adapters, it only renders the first level of the menu, all subsequent levels are not even displayed. I want to use filter for some transparency effect, but using it is not rendering any child menu's. Following is a example -

.PrettyMenu .AspNet-Menu-Vertical

{

position:absolute;

top: 87px;

left: 0px;

width:200px;

z-index: 300;

filter:alpha(Opacity=50);

}

Now it only shows first level and rest of the menus are not displayed, if I remove filter, it works fine but without transparency.

Reply will be much appreciated.
