/**
 * The Combobox is a text input field which can show a list of options via a drop-down PickList. <p> The set of options
 * will be filtered based on the current value in the text field, so only options that match what has been typed so far
 * will be displayed. The set of options can be derived from a ValueMap or dynamically retrieved from a dataSource.  See
 * the PickList interface for further settings. <P> The two most common use cases for ComboBoxItems are: <ul><li>With
 * {@link com.smartgwt.client.widgets.form.fields.ComboBoxItem#getAddUnknownValues addUnknownValues} set to true, the
 * ComboBoxItem acts as a  freeform text entry field with the picklist providing essentially a set of suggested completions
 * similar to a URL bar in a web browser.</li>     <li>With {@link
 * com.smartgwt.client.widgets.form.fields.ComboBoxItem#getAddUnknownValues addUnknownValues} set to false, the
 * ComboBoxItem acts similarly  to a SelectItem where a fixed set of options is available to the user and the text entry
 * field  is essentially used to filter which of these options are visible</li></ul> <P> Other commonly used settings to
 * configure ComboBoxItem behavior are:<br> - {@link
 * com.smartgwt.client.widgets.form.fields.ComboBoxItem#getDefaultToFirstOption defaultToFirstOption} - this will select
 * the first option from the pickList as a default value for the item - and<br> - {@link
 * com.smartgwt.client.widgets.form.fields.ComboBoxItem#getCompleteOnTab completeOnTab} which causes the current selection
 * in the pickList (if there is one) to be chosen when the user tabs out of the field, allowing a user to type a few
 * characters and hit tab to auto-complete to the first matched option. <code>completeOnTab</code> is automatically set to
 * true if {@link com.smartgwt.client.widgets.form.fields.ComboBoxItem#getAddUnknownValues addUnknownValues} is  false. <P>
 * ComboBoxItem does not provide built-in support for multiple selection.  For a Combobox that does provide such a
 * multiple-select feature use {@link com.smartgwt.client.widgets.form.fields.MultiComboBoxItem}.
