the theme is not as described .. files are missing, as present from the demo
It sounds like you're a bit confused!
You know, when we sell this product, we have written very clearly: "Zoa - Minimalist HTML Template".
This is just Zoa HTML Template, not Zoa Shopify/WordPress theme.
So it does not include the element you mentioned.
It's just an HTML Template, you can develop your own elements!
