Sortable: Set maximum number of items for a list?

[dwburdick]

Would it be possible to set a maximum number of items for a list? I'm using two separate lists -- a master and a user-selected list. I'd like to allow the user to move or clone a maximum of five items from the master list to the user-selected list. Thanks for the great tools.

Use advanced groups: https://github.com/RubaXa/Sortable/tree/dev#group-option

The link provided no longer works, and the solution isn't explained anywhere. Can anyone elaborate on how to create groups with a set maximum length?

@LeszekKicior The demo in the README has this example: https://jsbin.com/nacoyah/edit?js,output

The last qux Sortable will stop allowing items once it reaches a max length of 4 items.
