How to add visibility criteria and required criteria

You can control the visibility and required status of a field based on the values of other fields. Here's how to set it up:

1. Click "Content Settings" in the field editor screen.
2. If you want a field to be required, you can directly set its value to "1".
3. If you want a field to be required based on the value of another field, click the "Plus" button.
4. In the popup, define your criteria. For instance, select a field, change "Equal" to "Not Equal," and change "Static" to "Empty." This means that if the selected field is not empty, the field you're configuring will become required.
5. Similarly, you can add visibility criteria. This means that if a field is not empty, the field you're configuring will be visible; otherwise, it will be hidden.
