Modify Radio Button Document on Ubuntu For Free

It's fairly uncommon to actually want to allow the form to be submitted without any of the radio buttons in a group selected, so it is usually wise to have one default to the checked state.

To allow only one radio button to be checked from a bunch of radio buttons, make the name of all radio button same. For example the below code has 3 radio button but only one radio button can be checked: <input type="radio" name="gender" value="male" id="mRadio"> Male<br>

This process can be automated by looping through an array that contains all the possible values and creating a new radio button element for each item in the array. To dynamically create radio button using an array, use the concept of createElement() and appendChild().

In case we need to select a radio button by default, we need to check it as true. Whenever the radio buttons are checked as true, then it will be autofocused by default.

You can check a radio button by default by adding the checked HTML attribute to the <input> element. You can disable a radio button by adding the disabled HTML attribute to both the <label> and the <input> .

HTML <div class="radios"> <div class="radio-wrap text-center"> <div class="radio-label- text-center">1</div> <input type="radio" id="radio1" value="option1" name="radio1" class="text-center"> <label for="radio1"></label> </div> <div class="radio-wrap text-center"> <div class="radio-label- text-center">2</div>
