Drag & drop for navigation

[ABartsch]

I create a new MetaTreeBranch with two Child MetaTreeNode one for all Objects and one for the Folder of Objects and placed standard navigation in it. Everything works fine but the Drag&Drop feature is not available. How can I implement the drag and drop functionality? 

Thanks

For this you have to set the MetaAssociationEnd to navigable through drag&drop
or Properties->Characteristics.
