There are several predefined groups that can have a reference list styled so that the label (a character within square brackets with all superscripted, e.g., [1]) of a note or citation (aka footnote, reference) matches and links to the note marker label located in the main text and the label in front of the note's text in the appropriate group's list. There can be more than one of these groups' lists in the Notes, References and other similarly purposed sections. These predefined note and citation groups have templates that make the wikitext markup simpler. These templates also allow a standard reference to be inserted, so that an explanatory note can have a reference, or citations can be nested.Note: If the note's text has a reference name that is used more than once, the labels will still match, but the clickable alpha characters that toggle the note's display will be next to the note's label, with links to the multiple locations of its marker in the main text. See WP:REFNAME and the first point below in § Issues.In these examples, the footnote labels match between the footnote marker and the reference list:Lorem ipsum dolor sit amet.[lower-alpha 1] Consectetur adipisicing elit.[lower-alpha 2] Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.[lower-alpha 3]Lorem ipsum dolor sit amet.[lower-roman 1] Consectetur adipisicing elit.[lower-roman 2] Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.[lower-roman 3]Lorem ipsum dolor sit amet.[lower-alpha 1] Consectetur adipisicing elit.[lower-alpha 2] Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.[lower-alpha 1]Lorem ipsum dolor sit amet.[lower-alpha 1] Consectetur adipisicing elit.[lower-alpha 2] Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.[lower-alpha 1]
