HTML DOM Select Object

Select Object

The Select object represents a dropdown list in an HTML form.

A dropdown list lets a user select one or more options of a limited number of choices.

For each <select> tag in an HTML form, a Select object is created.

You can access a Select object by searching through the elements[] array of a form, or by using document.getElementById().
