Add a combo with autoExpand : true, like this

// combo with string items
new Combo({
    items    : ['Fanta', 'Loranga', 'Jaffa', 'Zingo', 'Orangina'],
    label    : 'Items as strings',
    appendTo : targetElement,
    style    : { marginRight : '.5em' },
    autoExpand : true
});

If you click on the arrow instead of the text field, the dropdown list will immediately disappear.
