16 * @class Ext.layout.AccordionLayout
17 * @extends Ext.layout.FitLayout
18 * <p>This is a layout that manages multiple Panels in an expandable accordion style such that only
19 * <b>one Panel can be expanded at any given time</b>. Each Panel has built-in support for expanding and collapsing.</p>
20 * <p>Note: Only Ext.Panels <b>and all subclasses of Ext.Panel</b> may be used in an accordion layout Container.</p>
21 * <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt>
22 * configuration property. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
23 * <p>Example usage:</p>
25 var accordion = new Ext.Panel({
26 title: 'Accordion Layout',
29 // applied to each contained panel
30 bodyStyle: 'padding:15px'
33 // layout-specific configs go here
40 html: '<p>Panel content!</p>'
43 html: '<p>Panel content!</p>'
46 html: '<p>Panel content!</p>'

54 * True to adjust the active item's height to fill the available space in the container, false to use the
55 * item's current height, or auto height if not explicitly set (defaults to true).
58 <div id="cfg-Ext.layout.AccordionLayout-autoWidth"></div>/**
59 * @cfg {Boolean} autoWidth
60 * True to set each contained item's width to 'auto', false to use the item's current width (defaults to true).
61 * Note that some components, in particular the {@link Ext.grid.GridPanel grid}, will not function properly within
62 * layouts if they have auto width, so in such cases this config should be set to false.
65 <div id="cfg-Ext.layout.AccordionLayout-titleCollapse"></div>/**
66 * @cfg {Boolean} titleCollapse
67 * True to allow expand/collapse of each contained panel by clicking anywhere on the title bar, false to allow
68 * expand/collapse only when the toggle tool button is clicked (defaults to true). When set to false,
69 * {@link #hideCollapseTool} should be false also.
72 <div id="cfg-Ext.layout.AccordionLayout-hideCollapseTool"></div>/**

85 * @cfg {Boolean} animate
86 * True to slide the contained panels open and closed during expand/collapse using animation, false to open and
87 * close directly with no animation (defaults to false). Note: to defer to the specific config setting of each
88 * contained panel for this property, set this to undefined at the layout level.
91 <div id="cfg-Ext.layout.AccordionLayout-sequence"></div>/**
92 * @cfg {Boolean} sequence

96 <div id="cfg-Ext.layout.AccordionLayout-activeOnTop"></div>/**
97 * @cfg {Boolean} activeOnTop
98 * True to swap the position of each panel as it is expanded so that it becomes the first item in the container,
99 * false to keep the panels in the rendered order. <b>This is NOT compatible with "animate:true"</b> (defaults to false).
