Template:Bengali Language Movement Source: en.wikipedia.org/wiki/Template:Bengali_Language_Movement
This template's initial visibility currently defaults to autocollapse, meaning that if there is another item on the page (a navbox, sidebar, or table with the 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:
{{Bengali Language Movement|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Bengali Language Movement|state=expanded}}will show the template expanded, i.e. fully visible.
