Restricted Input with <select>
Restricting input from a user means presenting the user with a finite number of choices. In WML, this means using the <select> tag to present the choices as a list of text items from which the user can select one or more. This section will detail the use of the <select> tag and its primary children—the <option> and <optgroup> tags.
To get started, let's look at the simplest use of the selection list. Listing 7.16 shows a deck with one card that creates a simple poll.
