I hope this message finds you well. I wanted to address an issue regarding the layout of your category page. The thing is when creating a custom layout we take care of these requirements. There are widgets available for “Sorting, Count, and Grid/list style” You can simply add them to your custom layout. You can view the widgets in the following image: https://postimg.cc/rdfn4rTK With the help of these widgets you will be able to achieve the product navigation bar on your custom layout.
If you require any further assistance with this matter, please do not hesitate to let me know.
Thank you for your time and attention.
