Concatenate Radio Form For Free

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().

You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes.

Defining Radio Group in HTML 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.

The HTML <form> element contains child elements that collect user input, such as <input type=?radio?>. To make a basic form with radio buttons in it, wrap your radio button grouping(s) in a <form> tag, and include a <button> of type submit at the bottom.

Note: The radio group must have share the same name (the value of the name attribute) to be treated as a group. Once the radio group is created, selecting any radio button in that group automatically deselects any other selected radio button in the same group.

We use the <fieldset> tag, to group related data in HTML forms. This tag creates a box around the related elements on the web page. The <legend> tag is used inside the <fieldset> tag to give a caption to the group or name to the group.

Add "name" attribute and keep the name same for all the radio buttons in a form. Hope that would help. Just give them the same name throughout the form you are using. All the radio buttons options must have the same name for you to be able to select one option at a time.
