Hi da1vea,
I started using this PCF last week. I'm having some problems, but the basics are working perfectly.
This tutorial helped me a lot, but it doesn't have everything I need to finish mine:

Basically the most important thing is to create a collection with the information you need, this collection you will need to set in the Items section of the main area of your Kanban. After that you will need:
1 - Activate the option "Master Zone = true" in the main column (In the case where you start your tasks, e.g. To do).
2 - Set the following zones that make up your Kanban to the "Other Drop Zone ids" option. If there are more than 1, you will need to separate them with a comma. Ex: "In Progress, Blocked, Done".
3 - You also need to set the DropZoneId, which must contain exactly the name of your Field Option in the table. In my case, I'm working with Task and the field I use is "statuscode". The option that starts my Kanban is "To do". In this case DropZoneId = "To do".
4 - Select the "ZoneColumn" option containing the name of the field in your table. In my case "statuscode".
5 - Set the IdColumn field. The id of your record in my case "activityid".
Basically, just with this, your items will appear in your app and you will be able to move the tasks between the columns in Kanban.
