Radio toggle allows the user to choose one of the grouped options. Use a radio toggle when there are two or more options that logically belong to a single group. It only allows exclusive selection; only one of the items can be selected at a time.
A radio toggle can be simply used to select one option, as well as to toggle among the different views of a part of a form. The different views would only present the applicable fields depending on the selection of the radio toggle.
A radio toggle should present visually clear distinction among selected, hover, and unselected. This may be achieved by the appropriate layout, spacing, and the use of color. Individual buttons should be labeled with text, an icon, or both.
Use cases: TV or Web episode selector
