Wonder if you guys can help me?

I want a dropdown box (easy), BUT, I want the content of the drop down box to be a series of checkboxes. I know it can be done in pure XHTML, but a combination of HTML/Javascript/DOM should work ... I think?

Also note, that when the user clicks on the dropdown list, the z-indez of that IFRAME or layer (what ever you use) must be on top of any other control. And, when a user checks on any of the control, and clicks anywhere on the body of the HTML form, the select box should have the values of the checkbox. And when the user clicks on the select box it should check the values the user has checked.

Hope I've made sense?

I know it sounds compliciated, I sure cant do it. Please let me know if its possible?
Thanks

How about something that "looks" like a select box, but when you click on it, it opens up as a "like" a select box with checkboxs?

well you can write a javascript function which is called when you select something from your pulldown, and then creates a checkbox in the DOM which itself shows your pulldown again with onmouseover event.

or use something like:

  <input type=checkbox ... id="check1" style="display:none" />
  <select name=pulldown >
     <option>string</option>
     <option>checkme</option>
   ...
    </select>

where you set the chekbox to display:visible ifyou have selected it.

As I said: not possible with option tag. Dot. Period.
Did you try my suggestion with the invisible checkbox, which gets displayedon change?

something like:
  <select name=pulldown onchange="document.getElementById('check1').style.display='visible'">

Note that you need to hide all others, and hilight only the one depending on your selection.
