Configuring jstree right-click contextmenu for different node types

Question

I\'ve seen an example somewhere online showing how to customise the appearance of jstree\'s right-click context menu (using contextmenu plugin).

For example, allow

Answer 1

Implemented with different node types:

$('#jstree').jstree({
    'contextmenu' : {
        'items' : customMenu
    },
    'plugins' : ['contextmenu', 'types'],
    'types' : {
        '#' : { /* options */ },
        'level_1' : { /* options */ },
        'level_2' : { /* options */ }
        // etc...
    }
});

And the customMenu function:

function customMenu(node)
{
    var items = {
        'item1' : {
            'label' : 'item1',
            'action' : function () { /* action */ }
        },
        'item2' : {
            'label' : 'item2',
            'action' : function () { /* action */ }
        }
    }

    if (node.type === 'level_1') {
        delete items.item2;
    } else if (node.type === 'level_2') {
        delete items.item1;
    }

    return items;
}

Works beautifully.
