Radio buttons?

How can a have one of those check lists where the person can select one answer only (radio buttons)?

Radio buttons allow the user to choose only one of a number of options. When you choose one option, any previously selected option is unselected. Radio buttons are grouped together by assigning them all the same NAME (but different VALUES).

<p>Which one of these old TV Shows do you miss the most?
<br /><input type="radio" name="oldtv" value="madaboutyou" />Mad About You
<br /><input type="radio" name="oldtv" value="fullhouse" />Full House
<br /><input type="radio" name="oldtv" value="stepbystep" />Step by Step
<br /><input type="radio" name="oldtv" value="partyof5" />Party of Five
<br /><input type="radio" name="oldtv" value="dawsonscreek" />Dawson's Creek
<br /><input type="radio" name="oldtv" value="buffy" />Buffy, the Vampire Slayer</p>

Like checkboxes, you can define a radio button to be checked by default, but unlike checkboxes you should only have one radio button in a group initially checked.

<p>Which one of these old TV Shows do you miss the most?
<br /><input type="radio" name="oldtv" value="madaboutyou" checked="checked" />Mad About You
<br /><input type="radio" name="oldtv" value="fullhouse" />Full House
<br /><input type="radio" name="oldtv" value="stepbystep" />Step by Step
<br /><input type="radio" name="oldtv" value="partyof5" />Party of Five
<br /><input type="radio" name="oldtv" value="dawsonscreek" />Dawson's Creek
<br /><input type="radio" name="oldtv" value="buffy" />Buffy, the Vampire Slayer</p>

Now you have Mad About You checked and set as default.

Remember: all the radio buttons in a group must have identical names (like in the example above - the name is set to "oldtv" for each option).
