tab post option

tab post option

It seems reasonable to have a post option with the tabs. 

It is possible currently to set the tab to post by changing the ajax method to post, however, there is no way to easily provide a parameter with the post. (forgive my missing it if there is). To have a post option with a url and param(s), would be most beneficial.

As another thought, if a callback could be added before the load, one could set the parameters for a post... this could also be useful for checking updates not saved, etc... 

Thanks,
