Meta Box

Hello,

You have misunderstood me i suppose.

In the image you can see that 2nd option is selected , and the other 2 options that take 3col width are hidden with conditions, i would want to achieve that they would not take that space if they are not visible and that selected option would always appear next to select option field. example bellow

That was the first thing i have done , forgot to inlcude in the list .

what i was trying to say i would like to asign class btn btn-default to "submit" button, is there a way to do so without JS with filters or somehow?
