For now, I don't think this can be done using just rmarkdown. However, you can produce an HTML document with a tabset section using rmarkdown and then tweak the HTML to convert the tab set to a dropdown menu. Alternatively, you can use the bsselectR package, which is unfortunately still in a somewhat-stalled development.

Below is an example of how you'd make an HTML document with rmarkdown and replace a tab set with a dropdown menu.

First, you'd write your rmarkdown document and then knit it to HTML.

---
title: "Tabset Example"
output: html_document
---

# The Tabset Section {.tabset .tabset-fade}

## First Tab
Here is the first tab's content.

## Second Tab
Here is the second tab's content
```

Then, in the resultant HTML file, you'd find this section of HTML:

    

        First Tab
    
    

        Second Tab
    

and replace it with this HTML:

 

     

        
          Choose a Tab 
        
        

          
First Tab
          
Second Tab
        
     

Which should result in your tab set appearing as a dropdown menu, such as the following:
