10## How to Use
11
12- Use radio buttons in a list with multiple options, where users can choose only one of them.

14- Do not use a single radio button. Instead, use a group of radio buttons. All the radio buttons in the group are equal.
15
16- You are advised to have the recommended option selected by default.
17
18- In case a radio button is selected as the recommended option, it can be cleared only when users select another radio button in the group.
19
20- Avoid using a radio button group for on/off options. Use a toggle instead.

22- After an option is selected, another option is deselected.
