how to show multiple options in combo

i have a multi select combo box(with check box) i want to make at least 5 options visible to user, with scrollbar to move down for more options. Like normal html select with size=5

pls help


combo doesn’t support such a functionality. You may use 2 dhtmlxgrids (or html tables) with 2 columns and hidden header. One of them (dropdown) is initialized in the absolutely positioned container and shown when the other grid is clicked.
