Editing Template:Navbox/Lua/doc (section)

=== Collapsing ===
The Navbox supports two forms of collapsing: for the navbox itself and for individual subsections.

;state = collapsed/<u>expanded</u>/plain
:This parameter controls the collapsing of the navbox itself. If set to <code>collapsed</code>, the box will be collapsed by default. If set to <code>expanded</code>, the box can be collapsed, but will be open by default. If set to <code>plain</code>, the box can not be collapsed and no Show/Hide link will show.

;state<sub>(n)</sub> = collapsed/expanded/plain
:Used to control the collapsing of a single section. A section goes from one header to the next. The number should thus correspond to the one of the header that is above the section to collapse. Options are the same as above.

;defaultstate = collapsed/expanded/<u>plain</u>
:Sets the default collapse state for the subsections only. Can still be overridden by individual <code>state<sub>(n)</sub></code> parameters.
