Scrollable MultiSelect (Multiple Select) DropDownList using jQuery

Hi Mudassar,

I tried your solution for multiSelect Dropdownlist and it worked well.

Multiple Select (MultiSelect) DropDownList with CheckBoxes in ASP.Net using jQuery

I've a list of over 100 items. Is there any way I can do pagination or scroll in the dropdown?  

I used the below css but dind't work.

.scrollable-menu
 {
   height: auto;
   max-height: 200px;
   overflow-x: hidden;
}
