I have 5 checkboxes and I was wondering if I could make it so that
when one
checkbox is ticked all the others can't or with some only certain
ones can be
ticked

Morning
Afternoon
Evening
Evening Extension
Special Booking

When morning is ticked nothing else can be ticked
Same for afternoon
When evening is ticked only evening extension can be ticked aswell
And finally when special booking is ticked evening extension is
ticked
automatically

If anyone could help I would be very grateful
