Pretty HABTM check boxes

Rails
1

I’m 100% positive this has come up multiple times before. I just
can’t find it for some reason. I’ve got a HABTM relationship, we’ll
just say Item HABTM categories. When I edit an Item via a form, I’d
like there to be check boxes for all the categories, and they’ll
obviously be checked if an Item has a relationship with a particular
Category. I’ve seen a message about something like this (fairly
recently i think) - anyone have a link?

Thanks,
Pat
