javascript - How do I limit the number of options displayed in an HTML Select element dropdown menu?

Essentially the length of the HTML Select drop down is exceeding the screen on notebooks, I've checked and different browsers allow different amounts of options to be displayed before it turns it into a scrollbox. Is there any way of putting in a browser css hack or javascript action to stop it at 3 options? Failing that is there any way to limit the height of the drop down for the same effect?

I've googled up on this but with no such luck, no one seems to have had a problem with notebooks before. I know it's possible as on the Lloyds TSB personal login screen there is a select element which limits to about 3/4 options. As I say I don't mind using JS or even browser specific solutions as I've developed a notebook friendly way of doing it which is less intuitive and clunky looking but can be used as a default.

Any help would be greatly appreciated.

Sadly, you can't change the item's that the dropdownlist displays, it is decided by the browser, with the size option it will loose its 'dropdownlist' form, and turn more into a list.

You could try finding some Jquery dropdown list, they are usually editable to whatever you want.
