Hide completed items from shopping list template

[danielrosehill]

I've been trying to get this working!

The shopping list HA integration is super basic and (unless I'm missing something) there's no operator to hide the completed/bought items from view.

I tried to see if I could find a CSS class and hide it using card-mod.

class="editRow completed " looked promising but didn't do the trick.

If there's any way to do this please let me know - I would love to document the feature and am sure many would appreciate it.
