Bootstrap 4 is a necessity for utilizing checkbox, select, and radio options

Is there a way to require multiple input elements like checkboxes or select menus within a group element?

I've attempted the following code, but it doesn't behave as anticipated.

    <div class="form-group aria-required="true">
         <div class="radio">
            <ul class="list-unstyled">
                <li>
                <input type="radio" name="radio1">
                <input type="radio" name="radio2"> 
                <input type="radio" name="radio3">
                </li>
            </ul>
        </div>
    </div>

Answer №1

The aria-required attribute is vital as it signifies the necessity of user input on an element before a form submission can take place. This attribute is not exclusive to elements with an ARIA role and can be applied to any standard HTML form element.

Although HTML5 now includes the required attribute, aria-required remains valuable for browsers that have yet to fully integrate HTML5 support.

Commonly Used in ARIA roles

  • Combobox
  • Gridcell
  • Listbox
  • Radiogroup
  • Spinbutton
  • Textbox
  • Tree

Example of a Basic Form Structure

<form action="post">
 <label for="firstName">First name:</label>
 <input id="firstName" type="text" aria-required="true" />
 <br/>
 <label for="lastName">Last name:</label>
 <input id="lastName" type="text" aria-required="true" />
 <br/>
 <label for="streetAddress">Street address:</label>
 <input id="streetAddress" type="text" />
 </form>
