    Default


    • renderTo renders the Component into the specified existing element.
    • applyTo uses the specified alement as the main elementof the Component. A Component created using applyTo does not need rendering - its main element already exists.
    • contentEl is only for Panels. It simply moves the specified element into the body of the Panel when the Panel is rendered to use... as the content!

    i added the config "renderTo: Ext.get('tree-div')" and it just does not work. tree-div is the id of a div in a form in body of the page.
    I am mixed up!
    help me please.

    Is this the body of a FormPanel? In that case you shouldn't be using renderTo at all!!!

    Instead, you should be specifying the component as one of the items of the formpanel.
