знать бы что делать, пока только html кодом могу обрадовать

<div class="row">
              <span class="label">Radio1 </span>
           
             
              <div class="frame">
                  <div class="radio-area">
                      <input type="radio" required name="radio1" value="1" id="o1">
                      <label for="o1">Radio 1<em>*</em></label>
                  </div>
                  <div class="data">
                    <input type="text" required id="o1" class="text1" name="field1">
                    <input type="text" required id="o2" class="text2" name="field2">
                   
                  </div>
              </div>
             
              <div class="frame">
                  <div class="radio-area">
                      <input type="radio" required name="radio2" value="1" id="o2">
                      <label for="o2">Radio 2<em>*</em></label>
                  </div>
                  <div class="data">
                    <input type="text" required id="o11" class="text1" name="field11">
                    <input type="text" required id="o21" class="text2" name="field21">
                    <input type="text" required id="o31" class="text3" name="field31">
