[html] How to allow only one radio button to be checked?

{% for each in AnswerQuery %}
    <form action={{address}}>
        <span>{{each.answer}}</span><input type='radio'>
        <span>Votes:{{each.answercount}}</span>
        <br>
    </form>
{% endfor %}

This is a part my django template, what it supposed to do is to print out several radio buttons, corresponding to the answers assigned to the buttons. But I don't know why I can check multiple radio buttons, which messed me up. It is supposed to only let me check on one radio button and I had that somehow but I lost it. Any help? Thank you.

All the radio buttons options must have the same name for you to be able to select one option at a time.

They need to all have the same name.

All radio buttons have to have the same name:

<input type='radio' name='foo'>

Only 1 radio button of each group of buttons with the same name can be checked.

Give them the same name, and it will work. By definition Radio buttons will only have one choice, while check boxes can have many.

<input type="radio" name="Radio1" />

Add "name" attribute and keep the name same for all the radio buttons in a form.

i.e.,

<input type="radio" name="test" value="value1"> Value 1
<input type="radio" name="test" value="value2"> Value 2
<input type="radio" name="test" value="value3"> Value 3

Hope that would help.

Just give them the same name throughout the form you are using.

<form><input type="radio" name="selection">
      <input type="radio" name="selection">
      ..
      ..
</form>
