Can I set width of jQuery's split button

At this URL ( http://jqueryui.com/demos/button/#splitbutton ) you can开发者_Python百科 see what I mean for splitbutton.

I would set the width of first button (the one which contain text). There is a way to do this?

In you CSS, you should include this:

.ui-button-text {
    width: 300px;
}

Or to whatever the desired width is.
