    <p>I have a Viewport and in Center region I have a tabpanel.Each tabpanel contain columns, and each column has panel with 3-4 items. Something like...</p> <p>Column A(Week 1) Column B(Week 2)<br> Item A1 Item B1 <br> </p> <p>Item A2 item B2</p> <p>I want these columns to be dynamic. If columns were a week of calendar then once the month changes,the columns also change.I also have a small calendar in the east region of this viewport and I am planning to trigger the column change using that calendar.</p> <p>Here is the code...</p> <pre><code>&lt;title&gt;Test&lt;/title&gt; &lt;link rel="stylesheet" type="text/css" href="../../resources/css/ext-all.css" /&gt; &lt;!-- Tabs Example Files --&gt; &lt;link rel="stylesheet" type="text/css" href="tabs-example.css" /&gt; &lt;!-- Common Styles for the examples --&gt; &lt;link rel="stylesheet" type="text/css" href="../shared/examples.css" /&gt; &lt;link rel="stylesheet" type="text/css" href="../../resources/css/ext-all.css"/&gt; &lt;!-- GC --&gt; &lt;!-- LIBS --&gt; &lt;script type="text/javascript" src="../../adapter/ext/ext-base.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="../../adapter/ext/ext-all-debug.js"&gt;&lt;/script&gt; &lt;!-- ENDLIBS --&gt; &lt;script type="text/javascript" src="../../ext-all.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="../../ext_main.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; Ext.onReady(function() { Ext.QuickTips.init(); var store = new Ext.data.Store({ data: [ ], reader: new Ext.data.ArrayReader({id:'id'}, [ 'id', 'St', 'GD', 'DC', 'T', {name: 'DP', type: 'date', dateFormat: 'Y-m-d'} ]) }); var viewport = new Ext.Viewport({ layout: 'border', renderTo: Ext.getBody(), items: [{ region: 'north', title: '', height: 24, xtype: 'toolbar', items: [{ xtype: 'tbspacer' },{ xtype: 'tbbutton', text: '', handler: function(btn){ btn.disable(); } },{ xtype: 'tbfill' }, { xtype: 'button', text: '&lt;b&gt;&lt;/b&gt;', menu: [ ]} ] },{ region: 'west', xtype: 'panel', title: 'Calendar', collapsible: true, split: true, width: 280, html:'&lt;object data=http://localhost:8084/TM/extjs/examples/layout/test.html width="400" height="220"&gt; \n\ &lt;embed src=http://localhost:8084/TM/extjs/examples/layout/test.html width="400" height="220"&gt; &lt;/embed&gt;&lt;/object&gt;' },{ region: 'center', split:true, xtype: 'tabpanel', activeTab: 0, items: [ { title: ' ', layout:'column', autoScroll:true, items:[{ columnWidth:.13, title: '2/21', xtype: 'panel', collapsible: true, items: [{ title: '', height: 100, dataIndex: '', rowspan:1, width:200}, { title: '', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ]} ] },{ columnWidth:.13, title: '3/14', xtype: 'panel', collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: '', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ] } ] } ] }, { title: '', layout:'column', autoScroll:true, items:[{ columnWidth:.13, title: '2/21', xtype: 'panel', collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: '', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ] } ] } ,{ title: '3/07', columnWidth:.13, collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: '', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ] },{ title: '3/14', columnWidth:.13, collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: '', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ] }, { title: '', layout:'column', autoScroll:true, items:[{ columnWidth:.13, title: '2/21', xtype: 'panel', collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: ' ', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ]},{ columnWidth:.13, title: '2/28', xtype: 'panel', collapsible: true, items: [{ title: '', height: 100, rowspan:1, width:200}, { title: ' ', height: 100, rowspan:1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 },{ title: '', height: 100, rowspan: 1, width:200 } ] } ]}, { region: 'east' }, { region:'south', height: 200 }); &lt;/script&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
