Any error from the browser console ?

Hi,

Is there anything in Episerver logs related to this?

I'm only seeing a console warning for this, it could be related (?)

No exceptions in the log either.

I know this is old, but we have the same problem and I suspect that it is not supported.

I testet with newest version and with quicksilver and I see the same there. When dragging from a item that is allready added, then you can't change order. You need to go to the "menu bar" on the item and press up/down.

If you drag in a new item from media, then you can drop it at the order you want.

No errors in the console

So I guess it is the [UIHint("commercemediacollection")] that doesn't support drag'n'drop on items allready added

I just checked it and it works fine for me. It's possible that you are editing non master language, in that case Assets (and the underlying CommerceMediaCollection property) is not editable.

This applies to the original question as well 

I'm editing the master language as we only have one language. Also, as mentioned, we can add new items and we can change order if we press the menu and select up/down

Adding a gif, maybe that explains more? Thats from the quicksilver demo project

Ah I see, I probably misread you. In that case yes, it is not allowed to drag and drop to reposition the assets. It has been too long for me to remember any reason why it's not supported, but it's the way it is for now. True you can argue that drag and drop will make a better experience but I don't think it will be added any time soon, or at all.

Good, because I used 1.5day to create a workaround using a new property of type IList<ContentReference> hooking up on PublishingEvent and finding out how IModelTransform works so the new IList get filled out with data from the CommerceMediaData if the IList was empty. (they only use "default" group so that is the reason why I could make the "workaround")

I guess it has something to do with the "groups", but thats just a guess from my site.

Thanks for confirming that it wont be fixed :)
