Multiple radio button groups in one form

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>

This is very simple you need to keep different names of every radio input group.

      <input type="radio" name="price">Thousand<br>
      <input type="radio" name="price">Lakh<br>
      <input type="radio" name="price">Crore
      
      </br><hr>

      <input type="radio" name="gender">Male<br>
      <input type="radio" name="gender">Female<br>
      <input type="radio" name="gender">Other

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>	

in input field make name same like

<input type="radio" name="option" value="option1">
<input type="radio" name="option" value="option2" >
<input type="radio" name="option" value="option3" >
<input type="radio" name="option" value="option3" >

To create a group of inputs you can create a custom html element

window.customElements.define('radio-group', RadioGroup);

to keep selected option in each group, you need to add name attribute to inputs in group, if you not add it then all is one group.
