A Collection is a group of Pages (sub-pages) that are related by theme. Depending on the number of pages in your Portfolio, consider creating multiple Collections.  Create a second Collection to showcase work you’ve done in a different field – like Graphic Design vs.  Illustration – or perhaps distinguish in another way – like Client Work vs. Personal Work – by creating two or more Collections. 

Once you have a handful of Pages, create a second Collection by using the “+” icon in the left side bar (or from Pages tab), and create another Collection by naming it, then choosing what Pages will be included in it. From there, you can use the Pages icon at any time to manage which Pages appear in which Collections by toggling them on/off, re-order within a Collection, rename, or make any other customisations you’d like.
