- * @class Ext.layout.AccordionLayout
- * @extends Ext.layout.FitLayout
- * <p>This is a layout that contains multiple panels in an expandable accordion style such that only
- * <b>one panel can be open at any given time</b>. Each panel has built-in support for expanding and collapsing.
- * <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt>
- * configuration property. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
- * <p>Example usage:</p>
- * <pre><code>
- var accordion = new Ext.Panel({
- title: 'Accordion Layout',
- layout:'accordion',
- defaults: {
- // applied to each contained panel
- bodyStyle: 'padding:15px'
- },
- layoutConfig: {
- // layout-specific configs go here
- titleCollapse: false,
- animate: true,
- activeOnTop: true
- },
- items: [{
- title: 'Panel 1',
- html: '<p>Panel content!</p>'
- },{
- title: 'Panel 2',
- html: '<p>Panel content!</p>'
- },{
- title: 'Panel 3',
- html: '<p>Panel content!</p>'
- }]
- });
- </code></pre>
