A Kanban board design is a relatively simple layout, composed of a few standard, repeating elements. Since elements like cards and the list containers are being repeated, it is best to start by building components for these so that as changes are made, they’ll be applied automatically to the instances by editing the main component.
The starter file provides three elements, a main list, a section header and a list item card. To get started, select the Main List group. With the group selected, right-click on the group and select Make Component. A component can also be created using the keyboard command Command+K on a Mac or Control+K on Windows or by clicking + on the Component panel in the top right.
