We need a form where people need to register for an interview, but we need to ensure a person can select multiple dates (like Dec 7, Dec 9, Dec 11) and times (9 a.m. on Dec 7, 11 a.m. on Dec 7, 3 p.m. on Dec 9 and 2 p.m., 4 p.m. for Dec 11) interview. Also, the next person choosing a date/time cannot select a date and time which has been reserved earlier by someone else. We are running Joomla 3.3.1
Which Joomla extension can do it? I heard Breezing forms would need lot of custom code for this.
