Unite Radio Form For Free

It is generally used in HTML form. If we want to deselect any option we have to select another option in the case of a radio button. Approach: To add a radio buttons in a webpage, the HTML provides a <input> element with type attribute is set to ?radio?.

A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items.

You can enable and disable the radio button by using the disabled property of HTML DOM. Set this property to true (disable=true) to disable the radio button in JavaScript.

To make it required that a selection must be made, just click the required option under Radio Button field settings. Doesn't matter whether you do this on just one of the radio buttons in the group, or all of them, you'll get the same behavior of ?one must be selected for this field to be valid?.

We can define a group for radio buttons by giving each radio button the same name. As and when the user selects a particular option from this group, other options are deselected. Following is an example of radio buttons with different names within a form.

To avoid having multiple radio buttons selected use the same name attribute. Radio buttons are normally presented in radio groups. Only one radio button in a group can be selected at the same time. The radio group must share the same name (the value of the name attribute) to be treated as a group.

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>
