The `trail` directive is supplied by the [[!iki plugins/contrib/trail desc=trail]] plugin. It sets options for the trail represented by this page, and can also add pages to the trail. Example usage: \[[!trail sort="meta(title)" circular="no"]] The available options are: * `pages`: adds pages that match a [[ikiwiki/PageSpec]] to the trail * `pagenames`: adds a space-separated list of pages to the trail, with the same [[SubPage/LinkingRules]] as for a [[ikiwiki/WikiLink]] * `sort`: sets a [[ikiwiki/pagespec/sorting]] order; if not specified, the items of the trail are ordered according to the first link to each item found on the trail page * `reverse`: reverses the [[ikiwiki/pagespec/sorting]] order * `circular`: if set to `yes` or `1`, the trail is made into a loop by making the last page's "next" link point to the first page, and the first page's "previous" link point to the last page [[!meta robots="noindex, follow"]]
