Field conditions on related entries

[wesort]

Following on from this Discord thread, I found it unintuitive how to conditionally show/hide fields based on the value of an Entries field. I tried the docs for Conditional Fields, but it doesn't include this.

Context

• A collection called Archive has an entries field called Archive type which allows users to select 1 (max items) entry from another collection called Archive type
• Elsewhere on the Archive blueprint, I need to show/hide fields based on what the user choose in Archive type.
  • eg: If they choose Video, then show the field Video meta info
  • eg: If they choose Photo, then hide the field Video meta info

Condition that does not work

• My instinct was to set the condition to equals video, but this doesn't work.
• I also stabbed around trying various combinations using contains, ===, prepending with $root and collection::archive_type::

Solution / Workaround

• get the ID of the Archive type entry of Video and use contains or contains_any (comma separating the IDs)

  
  if_any:
  archive_type: 'contains_any 7d9c28d8-dfb6-4d73-973f-8936f818109f, 484a539d-640d-4b86-b102-108a1cfbe777'

- The above will show the `Video meta info` field if a user chooses `Video` or `Interview` for the `Archive type`.

I could raise a PR for the docs if someone feels this would be useful. Being able to _select_ the relevant entries in the Conditions UI would be even better, but I'm not sure how many people using this approach.

I was thinking this might be a good use case for a custom field condition to query against the slug and makes this a bit more readable, but that probably doesn't work since the data inside the conditions would be just the id, right? So no way to query the slug without major contortions.
