jQuery Drop Down Hover Menu

Question

I\'m new to jQuery, I was hoping you guys could help me. I\'m trying to make a hover dropdown menu, but it\'s extremely buggy. Can you help me clean up my Javascript? Loo

Answer 1

To get a select box to open on hover to the exact height required by its contents, figure out how many elements there are:

JavaScript

function DropList(idval) {
    //
    // fully opens a dropdown window for a select box on hover
    //
    var numOptgroups = document.getElementById(idval).getElementsByTagName('optgroup').length;
    var numOptions   = document.getElementById(idval).getElementsByTagName('option').length;
    document.getElementById(idval).size = numOptgroups + numOptions;
}

HTML

    Any height
    etc.
