title: RMarkdown: How to end tabbed content
body: <p>Once I have defined tabs, how do I define content outside/below tabs? Or, how do I end tabbed content?</p>
  
  <p>I have planned a layout like so:</p>
  
  <pre><code>title
  content above tabbed region.
  
  tab1 tab2
  -------------------
  tab content 1
  -------------------
  content below tabbed region
  </code></pre>
  
  <p>which in rmarkdown would be</p>
  
  <pre><code>## title {.tabset .tabset-fade}
  content above tabbed region.
  
  ### tab 1 
  tab content 1
  ### tab 2
  tab content 2
  
  content below tabbed region.
  </code></pre>
  
  <p>But, <code>content below tabbed region.</code> appears as part of tab2. How can it be defined outside of the tab?</p>
  
  <p>Perhaps I might have further headings in content below. So a related question would be how can I define which headings to be part of tab and which ones not to be?</p>
