LuaGuiElement#elem_filters in examples mentions the hidden filter:

-- Then, there are some types of filters that work on a specific kind of attribute. The following will configure a
--   choose-elem-button of type "entity" to only show entities that have their "hidden" flags set.
button.elem_filters = {{filter = "hidden"}}

To me it implies that any hidden entry would explicitly be shown. When actually used, they don't:

Attached mod displays this GUI.

Sending as bug report because I assume it's unexpected behavior. If this happens to be a documentation issue, I'll make an appropriate interface request for something similar, because I'd like to show the player all the different item recycling recipes

Thanks for the report. I'm looking into this and I'm unsure how mods are wanting this to work. The base game applies several types of filters to select-buttons like this to auto hide stuff like hidden things, parameters, and other "probably don't want this to show" values.

Should these choose buttons in the modded case simply show *everything* always unless a mod filters them out? Right now they inherit the base games desire for how/what things show.
