[hadron_collider]

Hello,

I am trying to make the field "Reject reason" visible and mandatory to fill in in order to change the status.

[hadron_collider]

I mean: When approver click "reject" button there should be a field "reject reason" show up and mandatory

Better follow OOTB logic on Reject button

Keep teh field visible and put condition.

@hadron_collider ,

is the UI action "reject" client side?

You will need to make it client side, using the client checkbox, and in the script section use the 

g_form.setDisplay('reject_reason', true); and g_form.setMandatory('reject_reason', true);

mark helpful if this helped.

Thanks,
