This screencast shows how we can
- create a new Oxygen test site in the sandbox
- remove the unwanted Oxygen's meta box on certain admin screens
- create a ACF field group having a Repeater with two sub fields
- select the ACF Repeater inside Oxygen's Repeater component
- set Heading and Text components to show the selected sub field values
- use Dynamic Data condition to output the parent Section only if the Repeater is not empty.
