I am a little stumped with a list issue; I posted it on the List/Logic category since it really seemed to belong there, just in case you felt like taking a look: > [@Drop sublists with a False value in index '1'](https://forum.dynamobim.com/t/drop-sublists-with-a-false-value-in-index-1/60377): > > I have a lists of Sublists, and I would like to completely drop any Sublist with a value of “false” in the ‘1’ index.
