UI Sheets are packed with pre-built page content made up of multiple elements. Page content is stored in separate Designer files according to page content type (e.g., blogs, dashboards, ecommerce, headers/footers, social and more).
How to use
1. Open the .afdesign file for the page content type you want.
2. Select, then copy and paste content to your design file.
and the step 2
Choosing light or dark versions
On many of the UI sheets, you’ll have the choice of light or dark versions of each page content. These versions are stored on separate layers. From the Layers panel, hide the Light Version layer to work with the Dark Version layer (or vice versa).
