The warning always occurs when using Vue 3. What is the problem here?

In the example you provided, I always see these two types of warnings in the browser console.

<Card> was created with unknown prop ‘dragging’
<Card> was created with unknown prop ‘selected’

Hello @jmh.yy,

Thank you for the report! The warnings are related to the Kanban source code, not to the using Kanban with Vue3. We will fix the warnings in the future updates.

Nevertheless, the warnings are harmless and do not interfere with Kanban work.
So, you could safety continue exploring Kanban usage with Vue3.

Hello @jmh.yy ,
We have removed the warnings with the release of Kanban 1.5.7 .
