Calendar always visible – no popup

we would like to use datepicker to display the calendar on a form not as a popup of a field but a calendar always visible. We are trying to create a “request for appointment form”.

We tryed easyreservations plugin, but it is too functional for us (we don’t need the appointment management, just an email… but with the calendar always visible in the form all the time).

Thanks everybody for your help.

-(something like using datepicker in a div instead of a input text field)
-form -> calendar (always visible) + date-field (blocked but modified by calendar) + hour-minutes + name + email + phone
