I need set day reservation in monthly calendar with capacity more 1.
But i need when customer booking a day, and in that day capacity not full, this day can't reservable for other user.

It is possible have exclusive day with capacity more of 1?

Hello,

I am not sure that I understand, you can set capacity you need. Object can have for example capacity 5. First customer will book a day with capacity 1. It means that this object will be still available in that day with capacity 4.
If anybody book a day with capacity 5, it will disable it for other customers.

Day can be disabled only if object capacity is fully used.
