How to get multi layer menus for reverse lookups?

[Anonymous]

I'm seeing that it is possible to do a tree-based selection for reverse lookups on the help page under "Enable Reverse Lookup". I would like to do something similar, mainly setting up pipe fittings in a dynamic block to be able to pick the size (ie: 4", 6", 8"), and then the submenu popping out with the fitting options (90, tee, check valve, etc). Does anyone know of any tutorials to get a layered menu to show up in the reverse lookup?

hi!

if You mean this picture

then this isn't lookup table

This is block properties table

Oh, that makes more sense... Guess it was poorly worded? I can't seem to
get those menus to work even with the properties table though...

Awesome, thanks. I think I can probably make this work; I've been attemping to build a grid of pipe fittings with the rows being the size of the fittings and columns being the fitting type. Looks like I will only be able to build a single row and basically just have the pieces constrained in a way that the fittings can be properly scaled up from 4" to 6".
