Note to editors on how to manage collapsibility:

  • Use {{Indo-Iranian languages|state=collapsed}} to show this template in its collapsed (hidden) state.
  • Use {{Indo-Iranian languages|state=expanded}} to show this template in its expanded (fully visible) state.
  • Use {{Indo-Iranian languages|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.)

  • This template uses {{Navbox with collapsible groups}}. To show a particular section of the template while leaving the other sections collapsed, use: {{Indo-Iranian languages |Section}} where Section is one of "Old/Middle Indic", "Modern Indic", "Old/Middle Iranian", "Modern Iranian" or "Other". (Omit any speech or quote marks.)
    For example: {{Indo-Iranian languages |Modern Iranian}}
