Template:Opera topics
 | This template lists existing Wikipedia articles related to opera. It also includes links to sections of articles with significant coverage of a topic (but only if the article itself is not linked). It does not include links to table entries or list items in articles which are already included within the group of list articles. The "Miscellaneous" group includes articles which fit poorly into the other groups. |
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:
- <syntaxhighlight lang="wikitext" inline="1">{{Opera topics|state=expanded}}</syntaxhighlight> will show the template expanded, i.e. fully visible.
- <syntaxhighlight lang="wikitext" inline="1">{{Opera topics|state=autocollapse}}</syntaxhighlight> will show the template autocollapsed, i.e. 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, but if not, it is fully visible.
