How to apply red border for container on required checkbox validation
I have a group of dynamic layouts which in a flow action. On click of submit, "value cannot be blank" is shown on all the required fields as expected. In my case, as all the layouts are collapsed by default, it is difficult for the user to open every layout to find out where the required field. I cannot used validate rule as it will hit my performance.
I want to highlight the dynamic layout's container border as red color when at least one field inside it is thrown the required message.
Can somebody help me how to solve this requirement? PFA doc for design and application screenshots.
