Single product page

Good day,

Can anyone guide me with displaying information on a product detail page? This page is a custom template.

I created a product in the admin panel and added options. I have a page that displays my products. When one item is clicked, it takes a user to more information (product detail page) of that item.

I have an html template in the templates/content folder and a php page that utilizes content from that template in the templates/pages/ folder.

I am trying to add the dropdown options to the product detail page for the product that was created via the admin panel and sync that with the "Add to Cart" button.

I am not able to add the dropdown options. I tried utilizing perch docs, but it is not working for me.

Any assistance please?

Thank you
