- SelectOption(String label,String value,Bool chosen)
An option for selection. These can be used to make the <option> elements for a <select> or to describe a checkbox or radio button. The
value field may be left blank, in which case the contents of the
label field will be used in its place.
chosen field determines whether this option is initially selected when the page loads. The behaviour when multiple options in a non-multiple select or multiple radio buttons with the same name are marked as initially chosen is undefined, and so you should avoid this in your code.
