I am stumped on a function to show/hide drop down elements based on a user's selection. If a user selects a second item from the first dropdown list, then I want to show a related dropdown with two options. If a user selects the second option from the second dropdown, then I want to show a data field. Somehow this is not working quite right. I am using Coldfusion to dynamically populate the dropdown. Any help will be appreciated.

Show what code you have so far.
You will need Ajax on the client-side to call the Coldfusion script to populate the dropdown. The second part will probably be solved by JavaScript alone.
you can either use Javascript itself to do stuff like:
document.getEle mentById('id'). show();
document.getEle mentById('id'). hide();
or if you are talking about chained select you need to implement it by Ajax.
However, if you're using CF8, it has built in dynamic select support for <cfselect> tag.

Hi,
You can use DIV function.

A DIV element is not a function. Is that what you meant?

I'm using Internet Explorer 5.5 and 6.x.
Specifically, the problem is that navigation menues (written in

the menues (some of the menues are nested two and three levels). As
long as the mouse cursor remains *within* the options of the menues,
the option under the mouse cursor is...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
