That’s not possible, at least not out of the box.

While you could query the page chosen in the `ville` field, the options in the `lieu` field will only be updated after saving.

So you would need a custom field that listens to the first field changing.

However, I wonder if when you don’t use a query in the blueprint, but do the querying in a second field directly in vue, this could be solved without saving first… 🤔
