                                    <div class="ml-3">

                                        </div>

                                                <label class="custom-control-label" for="q1_2">5</label>
                                           </div>
                                        <div class=" custom-radio custom-control">
                                            <input type="checkbox" class="custom-control-input" id="q1_3" name="q1"
                                                value="3" formControlName="q1" />
                                                <label class="custom-control-label" for="q1_3">7</label>
                                            </div>
                                        <div class=" custom-radio custom-control">
                                            <input type="checkbox" class="custom-control-input" id="q1_4" name="q1"
                                                value="4" formControlName="q1" />
                                                <label class="custom-control-label" for="q1_4">3</label>

                                        </div>
                                        <div class=" custom-radio custom-control">
                                            <input type="checkbox" class="custom-control-input" id="q1_5" name="q1"
                                                value="5" formControlName="q1" />
                                                <label class="custom-control-label" for="q1_5">8</label>
                                             </div>
                                    </div>
                                </div>


                            </form>
                        </div>
                    </div>

                </div>
            </div>
        </div>
    </div>
</div>

我尝试过这种方式

<div class=" custom-radio custom-control">

                                              <label class="custom-control-label" for="q1_1">2
                                                  <input type="radio" class="custom-control-input" id="q1_1" name="q1"
                                                value="1" formControlName="q1" /></label>
                                          </div>

然后我无法检查。这不是检查。

Update2

这里是user863让步的地方。如果我对其他问题使用该方法，则单选按钮将显示内部答案。如果我同样更改css值，

.custom-control-label::after {
  left: 1.5rem!important;
}

然后正确显示。但是我不能手动更改CSS。因为我不知道答案的长度，所以所有问题的长度都不相同。

.custom-control-label::before,
.custom-control-label::after {
  left: 1.5rem!important;
}

Answer 1

这是使用自定义CSS的演示

.custom-control-label::before,
.custom-control-label::after {
  left: 1.5rem!important;
}

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<div class="form-group">
  <label class="control-label"> 1) What is the answer of 3 + 5?</label>
  <div class="ml-3">
    <div class=" custom-radio custom-control">
      <input type="radio" class="custom-control-input" id="q1_1" name="q1" value="1" formControlName="q1" />
      <label class="custom-control-label" for="q1_1">2</label>
    </div>
    <div class=" custom-radio custom-control">
      <input type="radio" class="custom-control-input" id="q1_2" name="q1" value="2" formControlName="q1" />
      <label class="custom-control-label" for="q1_2">5</label>
    </div>
    <div class=" custom-radio custom-control">
      <input type="radio" class="custom-control-input" id="q1_3" name="q1" value="3" formControlName="q1" />
      <label class="custom-control-label" for="q1_3">7</label>
    </div>
    <div class=" custom-radio custom-control">
      <input type="radio" class="custom-control-input" id="q1_4" name="q1" value="4" formControlName="q1" />
      <label class="custom-control-label" for="q1_4">3</label>
    </div>
    <div class=" custom-radio custom-control">
      <input type="radio" class="custom-control-input" id="q1_5" name="q1" value="5" formControlName="q1" />
      <label class="custom-control-label" for="q1_5">8</label>
    </div>
  </div>
</div>

更新向右移动，如果需要对齐，请使用固定的width（根据需要）

.custom-control-label::before,
.custom-control-label::after {
  left: unset!important;
  right: -1.5rem!important;
}

.custom-control-label { 
  /*width: 100px;  (if alignment needed) */
}

Answer 2

如果要计算总和，则需要使用aggregate(score~grp+gname,df,max)，因为一次只能选择一个单选按钮。参考：https://www.w3schools.com/tags/att_input_type_radio.asp

aggregate(grp~grp+gname,df,length)
