Assign Radio Title For Free

2 Answers. All radio buttons that share the same name and are controls in the same form are part of a group.This means that you have two radio groups, each containing one radio button. You need to put them in the same group (by making them share a name) if you only want one of them to be selected.

Here you see the three radio buttons, each with the name set to contact and each with a unique value that uniquely identifies that individual radio button within the group. They each also have a unique id , which is used by the <label> element's for attribute to associate the labels with the radio buttons.

Only one radio button in a group can be selected at the same time. Note: The radio group must have share the same name (the value of the name attribute) to be treated as a group.

Radio buttonThe radio class is a simple wrapper around the <input type="radio"> HTML elements.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> .

Definition and Usage Tip: You define radio button groups with the name property (radio buttons with the same name belong to the same group). The name attribute is used to identify form data after it has been submitted to the server, or to reference form data using JavaScript on the client side.

Selecting a radio button by default In this case, the first radio button is now selected by default. Note: If you put the checked attribute on more than one radio button, later instances will override earlier ones; that is, the last checked radio button will be the one that is selected.

To label a radio button, add a <label> element after the <input> element and insert a for attribute with the same value as the id of the associated <input> element. Then, write your label text in the <label> tag.
