Is this a bug?
Have a look at this Booking Calendar:
www.paintballingatquex.co.uk/index.php/booking-page
When a the user selects a booking, if they select the highest (colored) boxes, then the whole selection is highlighted. i.e. 2, 4 or 7 hours (boxes). However, if the user selects a box somewhere inside the booking times, then only this box is highlighted. This can be very confusing for customers.
For example. If I select to book on Monday, for a full day slot. If I select the orange 0900-1000 slot, the full day is highlighted. If I select 1000-1100 or any other box, then only this one hour slot is selected.
Is there any way, then when a box in the middle or below the top box is clicked, then also the whole fixed period is highlighted. i.e. 2,4 or 7 boxes.
