Add {{String-handling templates}} to the bottom of a documentation page of a template listed in the navbox.
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 names identifying the groups/sections (omit any speech or quote marks):
trim
IRL
anlys/tech
Note to editors on how to manage collapsibility:
Use {{String-handling templates|state=collapsed}} to show this template in its collapsed (hidden) state.
Use {{String-handling templates|state=expanded}} to show this template in its expanded (fully visible) state.
Use {{String-handling templates|state=autocollapse}} to show this template in its collapsed (hidden) state only if there is another template of the same type on the page. (This is usually the default.)
