I have a tree of categories with drag-drop enabled, to let me re-order the nodes of the tree. Additionally I have a grid, from which I can drop items onto the tree to add them to these categories. What I'd like would be for tree node drag-drop operations to allow any type of drop operation, but the drops from the grid to only use the 'appendOnly' drop option, so that items can only be added to categories, rather than being inserted before or after nodes.
I tried having multiple 'treeviewdragdrop' plugins but this resulted in a duplicate ID error.
Is it possible to have a tree view that has more than one drop group, with different drop operations specified for each group, or that uses multiple 'treeviewdragdrop' plugins?
