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:

• {{Main world championships|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
• {{Main world championships|state=expanded}} will show the template expanded, i.e. fully visible.

• Note, this template's contents are visible here but are set to be hidden ("collapsed") when it appears on other pages.
• Note, this template is not used for competitions for specific age groups.
