📻🔐 How to Allow Only One Radio Button to be Checked? 🚫🔘

Have you ever encountered a situation where you wanted to allow only one radio button to be selected, but instead, found yourself able to check multiple radio buttons? 😫 This can be frustrating, especially if you're working with a form or survey that requires users to make a single choice. But fear not! In this blog post, I'll guide you through the common issues and provide easy solutions to ensure that only one radio button can be checked. Let's dive in! 🏊‍♀️

The Problem: Multiple Radio Button Selections 😩

Consider this sample code snippet from a Django template:

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

The code intends to output multiple radio buttons, each accompanied by a label and a vote count. However, an unwanted behavior occurs, allowing you to check multiple radio buttons instead of just one. We need to address this issue – pronto! 🚑

The Solution: Grouping Radio Buttons 👥🔘

To allow only one radio button to be checked, you need to ensure that the buttons are grouped together. By grouping the radio buttons, you establish the rule that only one selection is allowed within that group. Here's how you can do it:

1. Wrap the radio buttons and their corresponding labels inside a <form> tag.

2. Assign a name attribute to each radio button within the form.

3. Ensure that each radio button has a unique value attribute.

With these steps, you'll create a group of radio buttons that work together harmoniously. Here's the updated code:

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

Now, when you run this code, you'll find that only one radio button can be selected at a time within the same group. Success! 🎉

A Bonus Tip: Improve User Experience with CSS 😍✨

While the functionality of allowing only one radio button to be checked is essential, you can enhance the user experience with some CSS styling. By adding custom styles to highlight the selected radio button, users can have a clearer visual indication of their choice.

Here's a CSS snippet to get you started:

input[type='radio'] {
    /* Add your desired styles */
}

input[type='radio']:checked {
    /* Add your desired styles for the checked state */
}

Feel free to customize the styles according to your needs and website design. 🖌️💅

By following the steps above, you can ensure that only one radio button can be checked at a time within a group. It's a simple solution to a common problem, and it keeps your form or survey experience user-friendly.
