How to adapt a site on bootstrap with a product catalog for a mobile device?

Question

Bootstrap

There is a website with a catalog of goods. Boostrap 3 was used for markup.
In normal mode, the product catalog is shown in the left column.
How in the mobile version to make this directory unfold on the screen when you click on the button. (hamburger menu)
I've looked at the navbar but can't figure out if it can be used for this purpose. It is used for horizontal menu.
Or you can use navs.
Tell me how to do it?
