This idea has been merged into another idea. To comment or vote on this idea, please visit WEBFLOW-I-161 Custom order for Collection Items.
Today we can only set the collection list 'sort order' by publish/update date or alphabetically/numerically. My clients often ask if they can set a custom order to promote or bump up some collection list items on the webpage.
If the designer and client could reorder the items in the CMS interface by drag-and-drop (same way as reordering new fields in the collection settings) AND this order could be a option in 'sort order' on the site, it would be a very powerfull feature.
