There are three options for creating a new kanban board.
From an existing SharePoint list—in this case, you need to choose a list you wish to use as a data source for your board. Traditionally, a task list is used for a kanban board, but you can use any custom list from SharePoint. If any required fields are missing, you’ll be able to add them in the board settings.
Create a quick board—if you don’t know which list to choose or you don't have an appropriate list already, you can create a quick board. When creating a quick board, the list with all the necessary fields and preferences will appear in the system automatically.
From a board template—Kanban Board Pro supports saving board templates. You can then use these templates when you create a new board.
