Information is supplied to the servlet
specified in the <form> tag by the pull-down menu and radio
buttons. For
example, if you select an item from a pull-down menu—bracketed by
<select> and </select> tags, and punctuated by
<option> tags—then the name identified in the <select>
tag and a string prefixed by an <option> tag are supplied to the
target servlet.
Thus, if you select Casablanca, then the
title–Casablanca name–value combination is supplied to the
target servlet.
<form ...> ... <select name=title ...> ... <option>Casablanca ... </select> </form>
