Neches Engineers-Position content outside JQM container

Neches Engineers-Position content outside JQM container

Hi 
I am Thomas working in Neches Engineers.
If for some reason, I have a specific DIV content inside data-role=header, How I can position it like usually we do for  css position:absolute ?
I tried but it appear only as  relative to header. I would like to make it position anywhere in the page.

Thanks
