    Default Ext.ux.form.CheckboxCombo


    This is very similar to Saki's LovCombo extension (, however it extends TriggerField rather than ComboBox and uses a CheckboxGroup internally rather than templates.

    Features Include:
    • Supports mostly all the same config options as a regular combobox
    • Works fine as a grid editor
    • Supports keyboard navigation
    • Tested in Chrome, FF, and IE8

    getValue() will return data like 'value,value,value', and you can use setValue() similarly, ie. checkboxCombo.setValue('value,value,value');

    As always, feedback is appreciated. Have fun with it!
