Visibility conditions
You can decide to show the selected field only when a specific condition matches.
You can set one or more conditions from available options and choose a relation between them.
- AND – Satisfy all conditions.
- OR – Satisfy any one condition.
If there is no visibility condition set, the field is always visible. Otherwise, it will be visible only when the condition is satisfied.
