Javascript/ASP : Horizontal scrollbar

This is not Possible....
Only way to do is to write your OWN Custom dHtml menu. it can not be done by Modifying your exisiting Tag.

I agree with the first response. It cannot be done using select. However, it can be done with CSS and simulating a select box.

I have working examples but they are not in the public domain. I will tell you that you need to use: overflow: scroll

I have written a CSS select box similar to size=2 or above and a drop down select box where size=1. The drop down comes it two flavors, one as a button to drop and close and one that drops and closes automatically.

I'm sorry I cannot provide code here but if you're familiar with CSS and javascript, you shouldn't have any problem working it out.
