Is it possible, if Radio Button is checked then a Text Field required?

enter image description here

We have 3 travel types, Car, Carsharing and public transport, if Car is checked the field "Mileage Start" must be required. Is there a solution without validation rule?


I dont think you can do this with configuration. Conditional required based on field values is not possible .

You other options are

  1. Validation rule(which you have mentioned)
  2. Trigger code
