I've started using this amazing datepicker by Keith Wood for my web project and was wondering if anyone could help me out.

I am trying to make it so when the user selects a day in any week, they can only choose 3 days more consecutively. 

What I have tried was using the multiselect however this allowed me to select any 4 days. I have also tried using the custom range method, which got me closer, when I tried to add an onselect function to the custom range method where the end-date selection have a maxDate of 4 days, the datepicker stops working.

Could anyone give any suggestions?

If I am unclear please tell me.

Thanks!
