You may be correct. (Depends on your exact use case.)

You’re looking for `:contains`. You might also have to use the “Advanced” condition to `:filter` a list of Things by the criteria “this Thing’s field-of-some-type :contains some-list-of-things-of-that-same-type”.

Such expressions can be difficult to build and are not possible in all cases. And, when possible, are not always particularly performant.

Bubble is array-oriented but (simultaneously) frowns on explicit iteration. Your own description of the problem says, “Hey, all I wanna do is iterate over some list.” But this is explicitly impossible in Bubble. _THERE IS NO ‘FOR’ LOOP IN (vanilla) BUBBLE._

There is, in fact, NO type of loop in vanilla Bubble EXCEPT for the implicit map-filter operation implied by the Advanced :filter parameter.

You can do this type of map-filtering using my List Shifter plugin (using the PROCESS List action), or by writing the correct Advanced filter operation in vanilla Bubble.
