Add any number of input elements inside the pearson-radio using the name attribute as the value you want to display for that input.

Forms can be tricky, so here is some guidance around how to implement accessibility successfully.

    <div class="gr-form-element">    <fieldset class="gr-fieldset">        <legend class="gr-label">This is a radio group</legend>            <div class="gr-radio">                <input type="radio" name="scotch" id="radioOne"  >                <label for="radioOne">Selection One</label>                <span>                    <svg focusable="false" class="icon-24" aria-hidden="true">                        <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#single-selected-24"></use>                    </svg>                </span>            </div>            <div class="error-state">                <svg focusable="false" class="icon-18" aria-hidden="true">                    <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#warning-18"></use>                </svg>                <span class="gr-meta">Warning Text</span>            </div>            <div class="gr-radio">                <input type="radio" name="scotch" id="radioTwo"  >                <label for="radioTwo">Selection Two</label>                <span>                    <svg focusable="false" class="icon-24" aria-hidden="true">                        <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#single-selected-24"></use>                    </svg>                </span>            </div>            <div class="error-state">                <svg focusable="false" class="icon-18" aria-hidden="true">                    <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#warning-18"></use>                </svg>                <span class="gr-meta">Warning Text</span>            </div>    </fieldset></div>
