I can't figure out the CSS to give each select button a minimum or fixed width. By default the width adjusts to the content but I want to have a minimum. I have several rows and I want them to stay aligned as the selection changes.

There are similar questions for non-jqm select boxes where the solution is simply setting width attribute, but that doesn't work here. 

Here is the jsfiddle:
