JQuery question

Hi.

Trying to solve the problem with IE7 displaying select boxes at the size of the select box, and not the content.

Found this: http://css-tricks.com/select-cuts-off-options-in-ie-fix/
but it starts with "I was already using JQuery so". I saw a lot of JQuery modules, but which one should I install for this to work?

Here's the code from the link above:
$(function() {

$(".ProductAttributesSelect")

.mouseover(function(){
$(this)
.data("origWidth", $(this).css("width"))
.css("width", "auto");
})

.mouseout(function(){
$(this).css("width", $(this).data("origWidth"));
});

});

Thanking you.
Shay.
