Within the element builder, architects and builders can add a checklist area (or multiple checklist areas) to an element – by clicking on the “add element content areas” action button (“+”) in the element builder action button panel and selecting “Checklist area”. Like all other content areas, they can then be placed (using the blue drag-drop action button) in any position. 

You can also import and existing checklist from another element, click on the relevant button and an off-canvas window will appear on the right, scroll through or search for the required checklist to import.
