Hi,
Welcome
I’m not sure if you imported Demo data, but if you imported Demo data (Classic demo), you’ll see home4 in the Page, and this page is the layout you want. But importing demo data will reset your settings such as font logos, etc. You can refer to this tutorial to import data.
You can also create this layout page by inserting a template. Refer to the Insert Templates section of this tutorial and choose to insert the home4 layout. You should create a few portfolios before creating this page, otherwise the portfolio list in the home4 page will be empty.
Regards!
