Indicated if to refresh during add/remove of nodes If you need to add a lot of nodes, it might be useful not to refresh during each operation. Set .skipRefresh = false to skip refresh when new nodes are added/deleted with the following functions

• w2sidebar.add()
• w2sidebar.insert()
• w2sidebar.remove()
• w2sidebar.set()

If you have a sidebar defined in the following way, you can add/remove/insert items let sidebar = new w2sidebar({ name: 'sidebar', skipRefresh: true, nodes: [ { id: 'id-1', text: 'Level 1', hidden: true }, { id: 'id-2', text: 'Level 2', expanded: true, nodes: [ { id: 'id-2-1', text: 'Level 2.1' }, { id: 'id-2-2', text: 'Level 2.2' } ]}, { id: 'id-3', text: 'Level 3' } ] }); Or any time after the object has been created: w2ui.sidebar.add([ { id: 1, text: 'Item 1', icon: 'icon-page' }, { id: 2, text: 'Item 2', icon: 'icon-page' }, { id: 3, text: 'Item 3', icon: 'icon-page' } ]) w2ui.sidebar.refresh()
