An enhanced version of the HTML SELECT tag, populated dynamically. It works
very nicely with very large data sets because it can load and page data as needed.
It also resembles ComboBox, but does not allow values outside of the provided ones.
If OPTION tags are used as the data provider via markup, then the
OPTION tag's child text node is used as the displayed value when selected
while the OPTION tag's value attribute is used as the widget value on form submit.
To set the default value when using OPTION tags, specify the selected
attribute on 1 of the child OPTION tags.
