Currently I'm trying to figure out if it's possible to attach the default contextmenu jstree uses, to a foreign node ?
To explain my scenario please go to this link and go to the bottom of the page. In the first demo you can drag'n'drop a foreign node (being "I have the jstree-draggable class") to the folders in jstree.
I'm trying to understand if it's possible to attach the jstree contextmenu plugin to that foreign node?
Yeah it's possible to attach contextmenu to foreign nodes in jstree. You should keep in mind, though, you'll need to rewrite a lot of code if you're using different html from what you have in the tree.
In my case this was not acceptable because I had to rewrite more than half of the library so I could get it to work with my html structure.
Creating a separate context menu (as @Jed suggested) is also an option - if you have the time to deal with all the problems that will come. :)
show_contextmenuin jstree source to have it accept non-nodes, or override it with your own method, maybe pilfering from the source as necessary. Since foreign contextual items should have less tree-relevant actions, it might be a good idea just to steal the code/style and create a separate context menu for foreign nodes. - glortho
