How to have date picker available for multiple users?

Eu perdi 3 formulários por não conseguirem desenvolver widget de reserva onde pudêssemos limitar a quantidade de reserva pelo calendário.  

Unfortunately, we don't have date reservation widget where the same date will be available for the next user. Date reservation widget reserves the chosen date.

If you want for any user to be able to select any date, you can use regular Date picker:

Let us know if you have any further questions.

Thank you!

Mas como poderia limitar as reservas mesmo serem colocados normal pelo Date Picker ?

Can you please clarify that you want to disable the Date/Time that was already selected by user on the form. The Date Reservation widget have this feature but not the Date Picker field.

You cannot use the Date Picker field to block/disable a selected date/time.
