- * <p>This class encapsulates a <i>collection</i> of DOM elements, providing methods to filter\r
- * members, or to perform collective actions upon the whole set.</p>\r
- * <p>Although they are not listed, this class supports all of the methods of {@link Ext.Element} and\r
- * {@link Ext.Fx}. The methods from these classes will be performed on all the elements in this collection.</p>\r
- * Example:<pre><code>\r
-var els = Ext.select("#some-el div.some-class");\r
-// or select directly from an existing element\r
-var el = Ext.get('some-el');\r
-el.select('div.some-class');\r
-\r
-els.setWidth(100); // all elements become 100 width\r
-els.hide(true); // all elements fade out and hide\r
-// or\r
-els.setWidth(100).hide(true);\r
-</code>\r
