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):
  • overview, "two-word groupname", concepts, details, related
  • For example: {{Collapsible sections option/doc |two-word groupname}}
  • The group/section named overview has been set to be visible when the template appears.
