InfoPath Dev

Hi there, I'm building a form in InfoPath 2010 and am trying to figure out how to get placeholder text, like what you can do with a textbox control, in a drop-down list box control that's bound to a data connection. Any suggestions or is this just not possible? Thanks!

 Yeah - you may be able to do this somehow in the form files - I'd probably just stick an expression box (calc'd value) over it with some help text and hide it if the drop down isn't blank...

That should work. Is there a way to actually have the expression box in front of or behind the drop down list control - that would be ideal but I can't seem to figure out how to do it... Thanks!

I actually found a way to do what I was originally trying to do. By setting the default value of the field that my drop down was bound to I was able to set the default text. With a quick formatting rule to emulate the grey text color this worked perfectly. I wouldn't call it ideal, but it gets the job done. Thanks for your help!
