- * @class 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.

- * Example:

-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);
