title: Extjs combobox displaying square bullet in dropdown list
body: <p>Here is the config for creating the combobox:</p>
  
  <pre><code>{
      xtype: 'combobox',
      id: 'state',
      fieldLabel: 'State',
      displayField: 'name',
      valueField: 'abbr',
      store: states,
      typeAhead: true,
      labelWidth: 35,
      padding: '0 10 0 0'
  }
  </code></pre>
  
  <p>The dropdown list display a square bullet infront of the the text - which I do not want and the highlight when scrolling the list does not highlight the entire line instead the space before the bullet and the bullet and first letter are not highlighted. I am using the ext-all-gray.css. I assume I need to override a style but have not been able to figure that out. Thanks.</p>
