Template:Random portal component/doc

This template generates a box for a portal home page. The content is drawn randomly from a pre-defined list.

Usage

 * header: (Optional) The header text of the box. If no header is passed to the template, the default is the subpage name.
 * footer: (Optional) The footer text in the box. E.g. Nominations for selected picture.
 * rootpage: (Optional) The root of the transcluded page, e.g. Portal:Foo.
 * subpage: The subpage of the transcluded page, e.g. Selected picture.
 * max: The maximum number of sub-subpages. Must be a positive integer.
 * seed: (Optional) The default seed is 17 and can be set to any other integer value (used to generate distinct values on the same page). Prime numbers work best, such as 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, and 113.

Formatting subpages

 * Create a sub-page first. If your portal is Portal:Foo, then a sub-page could be Portal:Foo/Selected bar.
 * On the Portal:Foo/Selected bar sub-page, place the template numbered subpages on the page and save it. The template will default to 50 subject sub-pages, however you can also use 25 Numbered subpages or 75 Numbered subpages for more or less sub-pages.
 * Once the list of subject links have been created, use one of the Selected subject templates from further to format each of the subject sub-pages.
 * This template calls /box-header and /box-footer for its color styles and closing, these must be present in your portal design for it to work correctly.
