/** * @class Ext.CompositeElement * @extends Ext.CompositeElementLite *

This class encapsulates a collection of DOM elements, providing methods to filter * members, or to perform collective actions upon the whole set.

*

Although they are not listed, this class supports all of the methods of {@link Ext.Element} and * {@link Ext.Fx}. The methods from these classes will be performed on all the elements in this collection.

*

All methods return this and can be chained.

* Usage:

var els = Ext.select("#some-el div.some-class", true);
// or select directly from an existing element
var el = Ext.get('some-el');
el.select('div.some-class', true);

els.setWidth(100); // all elements become 100 width
els.hide(true); // all elements fade out and hide
// or
els.setWidth(100).hide(true);
