How are radio buttons grouped?
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.
Why should radio buttons be in groups?
However, because radio buttons are mutually exclusive, you must group them together inside a RadioGroup . By grouping them together, the system ensures that only one radio button can be selected at a time.
How can you group a set of radio buttons together in HTML so that the user can select only one option amongst them?
As mentioned, radio buttons come in groups. Use the required name attribute to group together a set of related radio buttons. In the above example, all <input>s share the same value for name, so they are treated as part of the same group. This lets users only choose one option in a group at a time — try it out above.
Under what circumstances is a menu used instead of a radio button group?
Rule#1: When You Want to Emphasize Options
You want the user to read all options. The options are unfamiliar to the user and there is less or no chance that he can predict them.
What's the most important difference between checkboxes and a RadioGroup of radio buttons?
Checkboxes allow the user to choose items from a fixed number of alternatives, while radio buttons allow the user to choose exactly one item from a list of several predefined alternatives.
