Inputting Grouped List to "Values_" Input on Data-Shapes UI.Listview Data Node

Hi All,

What I’d like to do is have a list of unique floor types as the keys for the UI.Listview Data node, however, I would like for these keys to correlate to groups of floors (grouped by their type). Hopefully this makes more sense when read in conjunction with the image below:

I only want one of each floor type as the keys for the node, however, if someone was to select the BALCONY TILES key for example, I would like all 5 of the BALCONY TILES elements to be output from node.

I have found a workaround using the method below but was wondering if my desired method is achievable. Has anybody managed to do something similar?

Workaround:

I’ve attached the .dyn file just in case.

Thanks in advance!
