- * @class Ext.CompositeElementLite
- * <p>This class encapsulates a <i>collection</i> of DOM elements, providing methods to filter
- * members, or to perform collective actions upon the whole set.</p>
- * <p>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.</p>
- * Example:<pre><code>
-var els = Ext.select("#some-el div.some-class");
-// or select directly from an existing element
-var el = Ext.get('some-el');
-el.select('div.some-class');
-
-els.setWidth(100); // all elements become 100 width
-els.hide(true); // all elements fade out and hide
-// or
-els.setWidth(100).hide(true);
-</code>
