I develop a mobile website wit jqm 1.3.2 at the moment.

I need some forms with rows of label/form-element-pairs. or in other words: the label has to be at the left and the form-element on the right site. I found "Fieldcontainer groupings" but I want a side-by-side-behaviour up to 320px width. 

What is the best way, to realize that?

Should I use the field container-feature and overwrite it's CSS media queries ?

Or should I better use grids?

best,
