Can someone confirm that its not possible to change the height of a dropdown that is shown when you click on a select box.

The size attribute of the select makes it look like a list, the height attribute in the CSS doesnt do much good either.

Confirmed.

The part that drops down is set to either:

  1. The height needed to show all entries, or
  2. The height needed to show x entries (with scrollbars to see remaining), where x is
    • 20 in Firefox & Chrome
    • 30 in IE 6, 7, 8
    • 16 for Opera 10
    • 14 for Opera 11
    • 22 for Safari 4
    • 18 for Safari 5
    • 11 in IE 5.0, 5.5
  3. In IE/Edge, if there are no options, a stupidly high list of 11 blanks entries.

For (3) above you can see the results in this JSFiddle
