I have a couple places on my site where I'm intending to break down complex forms into various tabs. I can grok how to do this with additional nav menus and various block placements, but I would really like to have a standard UI visual indicator of what's going on, and I would really really like to not have to build one. (Especially since grokking Backdrop CSS is still on my to-do list, and hence I don't want to put anything fancy into that bucket.)
Any suggestions for out-of-the-box treatments? (Out of the box could mean installing new layouts or D7 modules known to work; I'm cool with that, but hoping to avoid any whack-a-mole with D7 modules that sort-of-but-not-really work.)
Excellent @themetman! ...I have a feeling that the Views Accordion module won't work in @jeffporten's case though, where he needs to use forms.
