question about field dependency / visibility

[Michael]

Hello, I have a question about field dependency / visibility: Can the master field that controls visibility also be located in an external collection?

I have two collections: ‘QSOs’ and ‘Repeaters’. In the “QSOs” collection, I can select a repeater from the ‘Repeaters’ collection via a link.

The ‘Repeaters’ collection includes the ‘Mode’ field, which can take the values “FM” or ‘DMR’ via radio buttons.

In the ‘QSOs’ collection, I would now like to show or hide a ‘Talkgroup’ field depending on the value in the ‘Mode’ field (show for “DMR”, hide for ‘FM’) .

Is this possible? Can I possibly copy the ‘Mode’ field from the “Repeaters” collection to the ‘QSOs’ collection?

Many thanks: Michael

Addendum: I tried using a lookup field, but it appears that this cannot be used as a master field for visibility control.

Hallo

Man kann mit hilfe von einem Skript Werte in ein Feld schreiben / Lesen . Du könntes in der Bibliothek in der du das Feld ausblenden möchtes ein Feld einrichten das sinen Wert vom " FM oder DMR " erhält . Von diese Feld machst du dann die Abhängikeit fest . Wenn du einen Neuen Eintrag erstellst wird automatisch das Feld ausgefült .

Hello

You can use a script to write/read values ​​to a field. In the library where you want to hide the field, you could create a field that receives its value from "FM or DMR". You then define the dependency on this field. When you create a new entry, the field will be automatically filled.
