How do I delete all checked items from a Trello checklist?

[Daniel Jiménez]

My Trello is extremely slow when I'm moving checklist items up and down. 

I discovered that when I delete all checked items (I've had to delete them one by one because I can't find a "delete all" button), it runs smoothly!

Hi @Daniel Jiménez 

   I think it can't be done
