/**
 * A MultiComboBoxItem is a combo box that allows the user to select multiple options.  Each selected option is represented
 * as a button that can be clicked to deselect the option. The relative layout of the buttons to the combo box is specified
 * with the {@link com.smartgwt.client.widgets.form.fields.MultiComboBoxItem#getLayoutStyle layoutStyle} attribute.  The
 * buttons will be kept in the order that they were added, with the most recently added button being adjacent to the combo
 * box. <code>MultiComboBoxItem</code> uses the {@link com.smartgwt.client.types.AutoChild} pattern to construct the {@link
 * com.smartgwt.client.widgets.form.fields.MultiComboBoxItem#getComboBox comboBox} and the {@link
 * com.smartgwt.client.widgets.form.fields.MultiComboBoxItem#getButton buttons} so that they can be easily customized.  For
 * example, you can customize the criteria used to fetch by  using {@link
 * com.smartgwt.client.widgets.form.fields.ComboBoxItem#setPickListFilterCriteriaFunction
 * ComboBoxItem.setPickListFilterCriteriaFunction()} with {@link
 * com.smartgwt.client.widgets.form.fields.MultiComboBoxItem#setComboBoxProperties setComboBoxProperties()}.
