Vorlage:IsIn
This template contains invisible RDF code to specify that the place referred to by a page "is in" a place referred to by another page. The site software uses that information to do various things, such as building a breadcrumb menu across the top of the page.
Note that this is only for destination guides. If you use it on other pages, you'll get breadcrumb menus all right, but you'll mess up other software. Please, don't do that.
To use it, add {{IsIn|name_of_other_place}} to the bottom of a destination guide. The name of the other place has to be in URL-encoded format, with underscores for spaces. The easiest way to get this format is to copy-and-paste from the location bar of your browser.
See Wikitravel:Breadcrumb navigation for more information, including tips for solving problems such as the breadcrumb menu not displaying properly.
