Multiple radio button groups in one form

问题:

Is it possible to have multiple radio button groups in a single form? Usually selecting one button deselects the previous, I just need to have one of a group deselected.

<form>
    <fieldset id="group1">
        <input type="radio" value="">
        <input type="radio" value="">
    </fieldset>

    <fieldset id="group2">
        <input type="radio" value="">
        <input type="radio" value="">
        <input type="radio" value="">
    </fieldset>
</form>

Set equal name attributes to create a group;

<form>
  <fieldset id="group1">
    <input type="radio" value="value1" name="group1">
    <input type="radio" value="value2" name="group1">
  </fieldset>

  <fieldset id="group2">
    <input type="radio" value="value1" name="group2">
    <input type="radio" value="value2" name="group2">
    <input type="radio" value="value3" name="group2">
  </fieldset>
</form>

Just do one thing, We need to set the name property for the same types. for eg. Try below:

<form>
    <div id="group1">
        <input type="radio" value="val1" name="group1">
        <input type="radio" value="val2" name="group1">
    </div>
</form>

And also we can do it in angular1,angular 2 or in jquery also.

<div *ngFor="let option of question.options; index as j">
<input type="radio" name="option{{j}}" value="option{{j}}" (click)="checkAnswer(j+1)">{{option}}
</div>
