Initial visibility
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{2021 shipwrecks|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{2021 shipwrecks|state=expanded}}will show the template expanded, i.e. fully visible.
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]).
