How to hide add action on a certain condition

[Aditya_K1999]

I have 2 tables, Service Booking & Service Availed in my app.

Service booking is a parent table & service availed is a child table. Now in the specific view I want the add action to be available on on a certain condition.

The condition is that the status of all the services under the booking, when it is not checked out, only then the add action should be visible, otherwise it should not be visible.
