How to setup a PORTFOLIO?
1. Create as many portfolio items ( Portfolio -> Add Portfolio Item ) as needed. Each portfolio item is one thumb on portfolio main page.
2. For each portfolio item set FEATURED IMAGE which will be used as thumb on portfolio page and check other options such portfolio format - image, video, gallery, audio etc... and fill in corresponding sections gallery format settings <--> gallery etc...
3. Create new page called e.g Portfolio and use page builder to add Portfolio module to it. Choose display options by clicking edit ( green button in top right corner of gallery module ) and categories to fetch - e.g You can display all portfolio images by selecting "All Items" or just certain categories - e.g landscape, people etc... - this technique allows You to create unlimited separate pages with different portfolios.
4. Choose page layout - sidebar etc... add text above/below via pagebuilder and publish page.
