View Full Version : DHTML Tooltip appears UNDER dropdown-menu (<select>)

06-23-2005, 06:24 AM
Are there really no workarounds for the problem with IE displaying dropdown menus ABOVE DHTML content?

I'm using THIS (http://www.dynamicdrive.com/dynamicindex5/dhtmltooltip.htm) script, and it's pretty annoying that the tooltip is shown underneath any dropdown-menus (select) in the page.

Is it possible for the script to detect those, and move the box if it detects one? (like it moves upwards, if you move the tooltip all the way to the bottom of the page, preventing being shown outside the page)

Does the drop down menu have a z-index set? If so, did you try boosting the z-index of the tool tip?

How do i specify Z-index on a drop down?

This image pretty much describes the problem: http://www.dynamicdrive.com/forums/attachment.php?attachmentid=35&stc=1 (my page is in a local html doc)

This does only happen in IE.

That's not a drop down menu, it is a drop down box. The only solution I know of is to temporarily make the drop box invisible while the tool tip is being displayed. Add to whatever code displays the tool tips that have this problem something that accesses that drop box's properties like:
document.getElementById('boxOne').style.visibility='hidden';Then, add to whatever code makes the tool tip go away:
document.getElementById('boxOne').style.visibility='visible';This assumes an id="boxOne" attribute is assigned to the problem drop box. It would be better to access the the box's properties as a document element in a form if it is but, not seeing your code, I cannot be sure if it is one. If this is only a problem in IE make it like:
if (document.all){document.getElementById('boxOne').style.visibility='hidden'};to allow other browsers to deal with it their own way.

Thanks for replying...

I have no experience with javascript :o - is your code supposed to be in the tooltip script, or in the drop down box?

Click here for my example page (http://www.dritbra.com/temp/tooltip.htm) (or see source at bottom of this post)

Where do i put the lines you gave me?

And do you mean adding "if (document.all)" would make Opera/Firefox not bother about it?

<style type="text/css">
position: absolute;
width: 150px;
border: 3px solid #2C8CBF;
padding: 3px;
background-color: #FFF;
visibility: hidden;
z-index: 100;

<div id="dhtmltooltip"></div>

<script type="text/javascript">

This will do it:
<div onMouseover="if (document.all&&!window.opera){document.all('select').style.visibility='hidden'};ddrivetip('Here is a tooltip that displays underneath the below dropdown')" onMouseout="hideddrivetip();if (document.all&&!window.opera){document.all('select').style.visibility='visible'};">Here is some text that will show tooltip</div>Just substitute that for the divison you have. It works off of the name of the select element. To avoid potential confusion it would be better to name the select element something other than select. Like:
<div onMouseover="if (document.all&&!window.opera){document.all('mySelect').style.visibility='hidden'};ddrivetip('Here is a tooltip that displays underneath the below dropdown')" onMouseout="hideddrivetip();if (document.all&&!window.opera){document.all('mySelect').style.visibility='visible'};">Here is some text that will show tooltip</div>

<select name="mySelect">
<option value="1">Dropdown value number one</option>
<OPTION value="2">Nokia 2</OPTION>
<option value="3">Nokia 3</option>
</select>It's possible to integrate this into the script but, if it is only for a few select (pun intended) boxes, it is not worth it.
