I\'d like to change the blue background color from IE when a drop down is focused, but I can\'t seem to find any CSS to do this.
I've been fiddling around with css and javascript and have searched the internet to find a solution. Unfortunately it looks like it's not possible to change IE's blue highlight itself. In the following example I've used a combination of CSS an JS to achieve nearly the same result in ie as you have on http://jsfiddle.net/TafDD/3/ . Have a look at it.
An example is worth a thousand words: (tested in IE7)
