True or False: Unless a radio button is grouped within another, only one radio button can be selected in an app interface.

The statement is true. In Alteryx interface design, radio buttons are specifically meant to allow the user to select only one option from a group of choices. When radio buttons are used, they are commonly grouped together to establish a clear relationship between the options. This means that within that single group, the user can only select one radio button at a time. If a radio button is not grouped with others, the expectation is that it operates independently, but the fundamental functionality remains the same: each individual grouping allows only one selection.

By default, radio buttons foster a mutually exclusive selection process to help users make choices without ambiguity, thereby enhancing the overall user interface and experience. The grouping is essential because it clarifies that the available options are related, ensuring that users understand their selections in context.
