GalleryAlbums display all albums

Possible? Have a gallery with four parent groups and 4-10 galleries inside each of those groups. I would think it'd be clearer, but is there a way to display ALL children of these parents on the front-end? I tried &showAll=`1` but just got the four top parents returned. Is there an unmentioned "&depth" switch out there? Thanks

any ideas at all? just need to get &showAll working in snippet call... [ed. note: pjldesign last edited this post 11 years, 7 months ago.]
