/** * @class Ext.dom.CompositeElement * @extend Ext.dom.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.dom.Element}. 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); */
