As already explained here without an answer: Hidden, nested components become searchable once they're used within main components
Once a hidden component is used within another component that is within a file it becomes searchable through the assets panel. Personally I don’t think this can be expected behaviour as the sole intention of hidden components is not to be searched for directly.
And there is another topic in regards to this:
- Hidden components should under no circumstance be found within a search.
- BUT: hidden components should receive updates when they’re updated & pushed from a library. Hidden components should then trigger an update within a file it is used.
