How can I use the form control in a drupal form? In Drupal forms API there is a control type called "form" which, I think, allows nesting forms inside other forms. There is no usage example out there and the search term is a bit tricky so Google couldn't help. Would you please tell me how can I use this control in my forms ?
Forms can not be nested in HTML. Since Drupal generates HTML, this should not be possible.
