I have been searching the interent for an age and couldnt find an answer. I was trying to change node text colour dependant on the type of the particular node. So in this example i wanted to change the text colour of every node that is a Role type defined in data.

    $(#roleTree).jstree({

        json_data: {

            data: roleTreeData

        },

        themes: {

            theme: default,

            dots: true,

            icons: false

        },

        ui: {

            select_limit: 1,

            select_multiple_modifier: none

        },

        types: {

            types: {

                AM: {

                    hover_node: false,

                    select_node: false

                },

                AF: {

                    hover_node: false,

                    select_node: false

                },

                Role: {

// i dont know if possible to be done here? add class?

             //   this.css(color, red)

                    //{ font-weight:bold}

                }

            }

        },



        plugins: [themes, json_data, ui, Select, types, crrm]



    }).bind(loaded.jstree, function (event, data)

    {

        $(#roleTree).jstree(open_all);

         data.inst.select_node('ul > li:first');



    }).bind(select_node.jstree, function (event, data)

    {

        selectedRoleId = data.rslt.obj.attr(id);

        window.selectedRole = GetRole(selectedRoleId);              

    });

}

Or any other method to highlight or tell users that only the role is selectable.
