__EXPECTED_UNCONNECTED_PAGE__

This navigational template collects links to portals and sister projects and displays them in a bundled box. It is an alternative to adding several floating box templates, which typically cause formatting issues because of their size and alignment.

It is intended to be placed at the end of an article, after the references, external links, navboxes and before any authority control template or categories.

Usage

No single parameter is required, however, at least one portal or sister project should be utilized with the use of this template. Since Wikipedia articles typically are in the domain of one or more WikiProjects, and since WikiProjects often have a portal, almost every article should list at least one portal.

Parameters

When copying all parameters in either the vertical or horizontal layouts, delete those which are not needed. If no links are needed for a particular type, such as the historical "books", that part of the template will not appear on the page. None of the parameters should be capitalized.

Parameter meanings (quick list). Alphabetical order: b: Wikibooks. commons: WikiMedia Commons. d: Wikidata. q: Wikiquote. s: Wikisource. species: Wikispecies. v: Wikiversity. voy: Wikivoyage. wikt: Wiktionary.

All parameters, horizontal. Parameters in order they show up in subject bar.

{{Subject bar|commons = y|species = y|voy = y|wikt = y|b = y|q = y|s = y|v = y|d = y|portal = }}

All parameters, horizontal. In alphabetical order, except for portal which is often removed.

{{Subject bar|b = |commons = |d = |q = |s = |species = |v = |voy = |wikt = |portal = }}

All parameters, vertical. In alphabetical order, except for portal which is often removed.
