So what we _really_ need is a way to group form elements. I worked on a site that needed this also. They ended up using the form templating commands in each ADP to arrange the elements the way the designer wanted to.
I think a simple way to group elements would be generally useful. The way grouped elements are presented could be determined by the form template.
One use, first_names, middle_initial, last_name on one line.
Another use is when extending a form. I might want to add an element in the middle of a form to keep related elements together when dynamically building a form.
