EXTJS comboBox multiselect

Question

In the ExtJS 3.3.1, I tried to make comboBox to multi select , but it doesn't 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");

Answer 1

There isn't a config option like multiSelect in Ext.form.ComboBox.
To get desired functionality you either need to develop a multiselect combobox by your own or use one of existing alternatives, like Ext.ux.form.CheckboxCombo, Ext.ux.form.SuperBoxSelect and Ext.ux.form.LovCombo.
