Use variation="list-button" when a list of links needs to be displayed in a seamless vertical stack. Note that the application needs to add any list structure and other semantic markup, like <nav>. Duet Link only provides the link, even if "list-button" includes the word "list". To include a caption like text, you can use <duet-paragraph size="small" color="gray-darker" margin="none"> as seen in the last example on this page.
