Hello everybody :)
I build Magento 2 in ubuntu 16.04 and bought Porto them from ThemeForest, I tried to customize it like [login to view URL] with the one-page category (I used Demo 19 which contain the one-page category feature ) now I changed my mind and I want to make it exactly like [login to view URL] (see the attached pictures) and you can go to [login to view URL] and see it.
my website to check what I have done: [login to view URL]
Please, only the expert in Magento and themes customization don't waste my time and yours.
Note: for more details see the screen capture explaining what I want.
