Parameters

 * image: Changes the image displayed in the top-right corner. Not recommended when used in the Signpost.
 * seriestitle: A succinct title of the series.
 * title1...title20: Up to 20 article titles (individual parameters).
 * date1...title20: Up to 20 article dates (individual parameters).
 * breakpoint: Number of articles to hide in a drop-down menu. Implemented in February 2015 to fix problems with series length creep affecting the formatting of older articles included in the series. Generally a breakpoint leaving five open stories and hiding the rest below is preferred in the case of large series.
 * toggle_title: Because of the way dropdown is implemented in the menu there has to be some unique, unspaced string in this parameter in order for this template to open individually on pages which have two or more series templates. If this parameter is not defined in such situations templates will both open when one is toggled. An example of a legal :  . An example of an illegal one: , or even.
 * custom_breakpoint: You can configure a breakpoint on one instance of a series that overrides the master breakpoint. Insert  in the master template, and then include   in your particular template, where   is replaced by the breakpoint number. Note that though possible this is generally not recommended (Res Mar  is currently looking into making the series template entirely collapsible as part of a larger series implementation overhaul).

Hosting
In the past series templates were hosted directly in the Wikipedia_Signpost/Templates domain, however as a result this domain has now become overcrowded with various deprecated and non-functional templates, making the useful ones harder to see in listings. New series should instead be hosted from Wikipedia_Signpost/Templates/Series. A list of such series follows:
