Usage edit
This is a simple navigation template based on {{Navbox}} that takes an optional state parameter:
{{Electricity delivery}}
The template is suitable for transcluding at the bottoms of articles relating to Electricity generation. Note that for many such topics, more specific navigation templates may be available.
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:
{{Electricity delivery|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Electricity delivery|state=expanded}}will show the template expanded, i.e. fully visible.
