Multi-word tags | Adding multiple things into a list from one input field

Ok, so this is an example of the multidropdown, with a box to add in “new” items, and the new item gets added to the selection (which is probably the tricky bit) when you add it.

The multidropdown works as standard, but it has a default set to a custom state. The custom state is kept in line with the values in the multidropdown, but gets added to when a new Artist is added, and then you reset the group to reset the values to add the new value.
