In Photoshop Elements I can sort pictures in a collection via drag and drop. How can I sort collections in LR5?
I've selected a collection with the sorting marker on adjusted order. Drag and drop doesn't seem to work.
Regular collections should allow drag and drop to change the sort order manually. You must start the drag by pointing at the photo thumbnail and not the grey area around the photo.
Smart collections do not allow manual sort order.
Collections in Lightroom can be sort by name or Kind.

Update:- I've realized that you are trying to sort Images manually.
So ,that's possible.Refer Quick Tip – Creating Custom Sort Orders in Lightroom « Julieanne Kost's Blog
