Being a total noob on all jQ / jQM / Javascript, I'm trying in mobile apps.

I learned that in a header section you only have the choice of max. 2 buttons inline with the header,  one being left, one right, heading text in between (as opposed to a footer section were you can have multiple icons / buttons).

But I want to have a selection box rather then a button on the left hand side, inlined in the header.

This  example  (  http://jsfiddle.net/5t50uzcz/ )

does not work (quite obviously), it is not in-line with the header and the gear icon, but how can this be achieved? Of course, I want the simplest solution, best a jQM only solution w/o too much extra javascript if possible.

Thanks for any hint!
