How to Create a “Yes/No” Radio Button

Using radio button to accept Yes/No questions is best because the field accepts only one of the options. It is better than a dropdown because there are only two choices - either of them can be selected by a single click

Here is the code to create a yes/no radio button.

<input type=”radio”  nameaffirmative  value=”yes”  checked>  Yes </input>  <input type=”radio”  namenegative  value=”no”>  No </input>
