Drilldown Sidebar menu for my bootstrap admin dashboard

I'm trying to make the sidebar navigation as a "drilldown menu" instead of the typical dropdown below menu. Is this possible, if so how?

Something like this: https://www.jqueryscript.net/demo/mobile-side-navigation-zeynepjs/#

My bootstrap theme: https://startbootstrap.com/previews/sb-admin/

I would really appreciate some help.
