### SelectElement

    protected SelectElement()

Method Detail

### as

    public static SelectElement as(Element elem)

  Assert that the given `Element` is compatible with this class and automatically typecast it.

### is

    public static boolean is(JavaScriptObject o)

  Determines whether the given `JavaScriptObject` can be cast to this class. A `null` object will cause this method to return `false`.

### is

    public static boolean is(Node node)

  Determine whether the given `Node` can be cast to this class. A `null` node will cause this method to return `false`.

### is

    public static boolean is(Element elem)

  Determine whether the given `Element` can be cast to this class. A `null` node will cause this method to return `false`.

### add

    public final void add(OptionElement option,
                          OptionElement before)

  Add a new element to the collection of OPTION elements for this SELECT. This method is the equivalent of the appendChild method of the Node interface if the before parameter is null. It is equivalent to the insertBefore method on the parent of before in all other cases. This method may have no effect if the new element is not an OPTION or an OPTGROUP.
