Example of tree.drop_mode with jQuery sortable anywhere

Question

Hello Everyone,

I have a working tree of galleries next to a sortable list of image thumbnails.

I've been vainly trying to set up the galleries tree so that users can add images to the galleries by dropping the sortable thumbnails on to the galleries tree.

I've been told this requires drop_mode. All efforts to get it to work have failed and I can't really make heads or tails of the drop_mode documentation.

I've sought out some working examples via Google of just such an application but have failed.

Can anyone point me to a working example of either a draggable or sortable list that successfully drops on to a tree and passes along some parameters between the two?

Thanks!
