Make multiple-select to adjust its height to fit options without scroll bar

Question

Apparently this doesn\'t work:

   select[multiple]{
     height: 100%;
   }

it makes the select have 100% page height...

auto

You can only do this in Javascript/JQuery, you can do it with the following JQuery (assuming you've gave your select an id of multiselect):

$(function () {
    $("#multiSelect").css("height", parseInt($("#multiSelect option").length) * 20);
});
