I'm trying to implement ecommerce template in my asp.net application. However, the template is broken a little. If you open this page (https://mdbootstrap.com/snippets/standard/mdbootstrap/2515460) which has main e-commerce page showing, you can click on "categories" link in navigation which opens up a sidenav. This works well on my project aswell. However, if you navigate to product page template (https://mdbootstrap.com/snippets/Standard/mdbootstrap/2515476) if you click on categories nothing happens. I can't make it work on my project aswell. Need help resolving this.
