How to display the message below the comboBox dropdown

I created a comboBox,

var states = Ext.create('Ext.data.Store', {
    fields: ['abbr', 'name'],
    data : [
        {"abbr":"AL", "name":"Alabama"},
        {"abbr":"AK", "name":"Alaska"},
        {"abbr":"AZ", "name":"Arizona"}
    ]
});

Ext.create('Ext.form.ComboBox', {
    fieldLabel: 'Choose State',
    store: states,
    queryMode: 'local',
    valueField: 'abbr',
    renderTo: Ext.getBody(),
    // Template for the dropdown menu.
    // Note the use of "x-boundlist-item" class,
    // this is required to make the items selectable.
    tpl: Ext.create('Ext.XTemplate',
        '<tpl for=".">',
            '<div class="x-boundlist-item">{abbr} - {name}</div>',
        '</tpl>'
    ),
    // template for the content inside text field
    displayTpl: Ext.create('Ext.XTemplate',
        '<tpl for=".">',
            '{abbr} - {name}',
        '</tpl>'
    )
});

below the drop down I wanted to display some messages.

Can anybody give some idea which component I will use or how to display some message below the drop down. Please check in screenshot.
