The purpose of the {{Universe navboxes}} template is to provide a structure to ease navigation between the many space- and universe-related navigation templates. Feel free to restructure it to add further clarity.
Templates using the classes class=navbox ({{navbox}}) or class=nomobile ({{sidebar}}) are not displayed on the mobile web site of English Wikipedia. Mobile page views account for approximately 66% of all page views (90-day average as of January 2024[update]).
Collapsible options
How to manage this template's collapsible groups/sections option
This template includes collapsible groups/sections. When it first appears, one of these groups/sections may be set to be visible ("expanded") while the others remain hidden ("collapsed") apart from their titlebars. To achieve this, include the parameter|name where name is one of the following words that identify the groups/sections (omit any speech or quotation marks):
astronomy, Solar, stars, PGO
For example: {{Universe navboxes |astronomy}}
This template's initial visibility currently defaults to collapsed, meaning that it is hidden apart from its title bar.
To change this template's initial visibility, the |state=parameter may be used:
{{Universe navboxes|state=expanded}} will show the template expanded, i.e. fully visible.
{{Universe navboxes|state=autocollapse}} will show the template autocollapsed, i.e. if there is another collapsible item on the page (anavbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar, but if not, it is fully visible.
