RMarkdown: How to end tabbed content

Use {-} for removing the TOC numbers, after ending the tabbed content

tab content 2
## section 2 {.tabset .tabset-fade}
### tab 1 
tab content 1
### tab 2
tab content 2
### tab 3
tab content 3
## {-}
content below tabbed region

My approach to this problem is simple, but it works:

## title {.tabset .tabset-fade}
content above tabbed region.

### tab 1 

tab content 1

### tab 2

tab content 2

##

content below tabbed region

The tab works only for 'sub-headers of the header with the.tabset attribute to appear within tabs rather than as standalone section' (see here)

So you just have to define a new header (in this case no title) one level above the tabs to signalize RMD not to be in a tabbed section.

It is also possible to design a document with different tabs in different headers:

## section 1 {.tabset .tabset-fade}
content above tabbed region.

### tab 1 

tab content 1

### tab 2

tab content 2

## section 2 {.tabset .tabset-fade}

### tab 1 

tab content 1

### tab 2

tab content 2

### tab 3

tab content 3

#
content below tabbed region

Edit: If you want to use a Table of Content (TOC) there is a problem with the solution above, because the last # will create an empty entry in the TOC. The solution here is to use

## {.unlisted .unnumbered}

content below tabbed region
