Is there a way to directly use bootstrap admin template?

I want to download a bootstrap admin template for creating a dashboard and want to generate graphs and plots through R. Is there a way I can do that without rearranging all the css and html codes.

Because most of the time these admin pages have so many js and css files that it's hard to rearrange them.

If there is any such way I want to learn it. Please do reply.

I find it hard to manipulate shiny objects through html.
