Styling a YUI Split button

Question

I want to use split buttons for a left side menu. I tried adding the class following.

<STYLE TYPE="text/css"> .catbutton { display: block; } </STYLE>

The buttons were the right width but the menu arrow was the section taking up the variable width. Not only was it ugly but the menu activation section was in the correct place on the far right. Clicking on the triangle which was floating in the middle did not work.

I was thinking that maybe I could add a <br/> element after the button using JS. I am not having any luck.

Help is appreciated.
