jQuery Dynatree Plugin - how to disable a node?

Question

http://wwwendt.de/tech/dynatree/index.html

Is it possible to disable individual nodes? If so, how?

Answer 1

Currently there's only the 'unselectable' node attribute. A workaround could be to let the onQueryActivate callback return false. And maybe add a custom class using the 'addClass' node option, to change the visual appearance.

Answer 2

$("#tree").dynatree({
        […]
        onActivate: function(node) {

          node.data.unselectable = true; //make it unselectable
          node.data.hideCheckbox = true; //hide the checkbox (more for UI purposes)

          node.render(true);


        },
        […]
    });

would disable the node on the fly

Answer 3

You can also use the unselectable and hidecheckbox properties directly while creating the dynatree node.

This was exactly what I needed, I wanted to have certain parent items unselectable in the tree.
