EXTJS comboBox multiselect

In ExtJS 3.3.1, I tried to make comboBox for multiple selection, but it does not work.

Please, help.

var mArray = new Array("ALL", "AAA", "BBB"); var mCombo = new Ext.form.ComboBox({ id: 'ID', fieldLabel: 'ID', triggerAction: 'all', height: 100, width: 163, multiSelect: true, store: mArray }); Ext.getCmp('mCombo').setValue("ALL");

There Ext.form.ComboBox no configuration option in Ext.form.ComboBox , for example multiSelect .
To get the desired functionality, you need to either develop a multi-second drop-down layout yourself, or use one of the existing alternatives, for example Ext.ux.form.CheckboxCombo , Ext.ux.form.SuperBoxSelect and Ext.ux.form.LovCombo .
