I'd like to do a couple of things in a bootstrap form, but not sure the syntax.
1. Explicitly put elements in a group on two lines, i.e. manually add a "br" or "" or something like that, so that it doesn't put a horizontal line or new section break between the items. (I think this is done with $group->add(new Form_Element(SOMETHING_HERE));?)
2. Make a text input box full width, or expand to occupy whatever horizontal space it can, rather than a fixed short width, where the string is expected to be (possibly) long.
Thanks for helping.
