For action set what is the use of On load and subscribe/Callback options

On a section on the Dynamic layout Actions tab itself i can see event as on load and then action as Subscribe and Callback. I wanted to know what are they doing?

Attached screenshot of the same.

Hi@TanyaS58

Please follow the below links to better understand on load event action set in dynamic layouts.

@TanyaS58

The section will automatically refresh (without any manual intervention) based on some events. For example: if there is a new row added to the table behind the scenes and then you trigger a notification for the section rules to refresh to see the updated values.

Please find the link for more details.
