/**
* @class Ext.layout.Accordion
* @extends Ext.layout.FitLayout
* <p>This is a layout that contains multiple panels in an expandable accordion style such that only one
* panel can be open at any given time. Each panel has built-in support for expanding and collapsing.
* This class is intended to be extended or created via the layout:'accordion' {@link Ext.Container#layout}
* config, and should generally not need to be created directly via the new keyword.</p>
* <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
* the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout.
* 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>
