Tooltips will be displayed in IE7 but not in IE6. I've heard from others this is because in IE6, when you click on a drop down box the browser gives control to the Operating System, so the browser doesn't know anything about where the mouse is or what it's hovering over, so it doesn't trigger the onmouseover event to display a tooltip.

To add the title attributes with Javascript you need to call the addTitleAttributes() function somewhere in your HTML after the drop down box is set.


You shouldn't need any onmouseover event in the <select> tag.

If your just coding in plain HTML you can just add the title tag to each OPTION in the SELECT, you don't need to use Javascript.


I just needed to add them with Javascript because I was generating the drop down menu with JSF's selectOneMenu which doesn't allow you to add a title attribute for each option when you're coding it.
