I have a Channel with 4 custom fields which represent half hour timeslots (10-10.30, 10.30-11 etc) - the idea is that the field is populated with the logged in users name to marry them up for an appointment in the required slot. So far so good.
Each person can only choose ONE timeslot so when in an ChannelForm to add/edit/remove their name in the field I would like them to see a drop down where they can choose from the four timeslots (i.e. fields) and then submit (their name can be passed in a hidden field).
This is rather than have a Channel-Form template which actually shows the four fields...in effect it is forcing them to choose one and not allowing them to see the four empty fields...make sense?
Is it doable?
