Activating "Select All" Tick Box in Multi-Row Form

Been away from SC for a while and I’m not sure what controls this feature any longer.

I have form apps that display records in 10 rows per page to allow user to select and delete. Some display the tick box to select all in the header row, some do not (see screenshot.) What exactly controls this?

I think that you are looking for the Mark every column option

Thank you. This is for user-created checkbox. However a multiple-record form opened in edit mode has scriptcase-generated tick boxes on the left automatically which allow you to select multiple items and then delete. That’s the one I am trying to get “Select All” tick-box on.

I’ve reviewed my old code and it seems I was only able to achieve this with grid apps and "Run’ button.

Javascript button will do the job

to check all
$(‘tbody tr td input[type=“checkbox”]’).prop(‘checked’, true);

to uncheck all
$(‘tbody tr td input[type=“checkbox”]’).prop(‘checked’, false);

Awesome, will give it a shot. Thank you
