---|
| 10 | * <p>This is a layout that manages multiple Panels in an expandable accordion style such that only |
---|
| 11 | * <b>one Panel can be expanded at any given time</b>. Each Panel has built-in support for expanding and collapsing.</p> |
---|
| 12 | * <p>Note: Only Ext.Panels <b>and all subclasses of Ext.Panel</b> may be used in an accordion layout Container.</p> |
---|
| 13 | * <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt> |
---|
| 14 | * configuration property. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p> |
---|
| 15 | * <p>Example usage:</p> |
---|
| 16 | * <pre><code> |
---|
| 17 | var accordion = new Ext.Panel({ |
---|

---|
| 19 | layout:'accordion', |
---|
