collapsed(defaults toTRUE) controls whether

attribute to headers within a document. This will cause all sub-headers of
the header with the .tabset attribute to appear within tabs rather
than as standalone sections. For example:## Quarterly Results {.tabset}
### By Product
### By Region
You can also specify two additional attributes to control the appearance and
behavior of the tabs. The .tabset-fade attributes causes the tabs to
fade in and out when switching. The .tabset-pills attribute causes
the visual appearance of the tabs to be "pill" rather than traditional tabs.
For example:
## Quarterly Results {.tabset .tabset-fade .tabset-pills}
