Good Morning @danbolinson @hugetim
Its been quite busy lately thus I have not come around to share a more updated Version.
However I’ve put together a custm component that should meet your needs.
https://anvil.works/build#clone:BWY2CQ6QCNHO5DE3=PUQXHHNMUQGEBHRN3CSFBLEM
You can give it a list of dicts, which are then displayed as a draggable list.
With the method get_sort() the component returns the sorted result.
You should be able to figure out the rest via the code pretty quickly.
Use the clone the link above and give it a try!
Greetings Mark
