HTML customizing Select tag

I have this Code For example:

<select >
  <option value="volvo">Volvo</option>
  <option value="saab"&g开发者_如何学Pythont;Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
  <option value="audi">Audi</option>
<option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option><option value="audi">Audi</option>
</select>

Its drop down is too long for me. Is it possible to set the height for the drop down. like setting it to 4 then if the entries are greater that four, the scrollbar will show.

I do not believe there is a way to do this as it is part of the browser specific rendering. If you look on different operating systems, the dropdown box displays with a different look and feel, and I believe that the number of entries shown before having a scroll bar is a part of that look and feel.

I know this question has came up before, and unfortunately I cannot find it in the archives, however I believe that you cannot edit the number of entries before a scrollbar appears.

Found another question that confirms this: Change Style of Scrollbar in DropDownlist in asp.net
