Documentation for Bootswatch suggests I can use a dropdown menu from a tab in a tabset:
How can I achieve this with Rmarkdown? I've tried:
# SECTION 1 {.tabset .tabset-fade}
## Section 1.1
## Section 1.2 {????something here?????}
### Section 1.2.1 <<<<<<<<< want this to appear under the dropdown menu
