contextmenu plugin enables a contextual menu to be shown, when the user right-clicks a node (or when triggered programatically by the developer).
Whether to select the right clicked node when showing the context menu. If this is set to
true and the node is not selected all currently selected nodes will be deselected.
Whether to show the context menu just below the node, or at the clicked point exactly.
Expects an object or a function, which should return an object. If a function is used it fired in the tree's context and receives one argument - the node that was right clicked. The object format is:
.show_contextmenu ( node , x, y )
Shows the contextmenu next to a node. Triggered automatically when right-clicking a node.
This can be a DOM node, jQuery node or selector pointing to an element within the tree.
The X-coordinate to show the menu at - may be overwritten by
show_at_node. If you omit this the menu is shown aligned with the left of the node.
The Y-coordinate to show the menu at - may be overwritten by
show_at_node. If you omit this the menu is shown just below the node.
