Hello anna,

Regarding the first question, I was not able to reproduce this problem.
Could you please check if the issue appears in this demo: https://github-r8z6a4.stackblitz.io
If it does, please share your web browser version.

Regarding the second question, can you please clarify what you mean by “storing”?
Our Kanban component supports exporting the current state of the kanban in an external file – pdf, html, json, xlsx etc. (You can see demo here)
If you mean getting or storing the current state(for example which tasks belong to which columns), you can use the “getState()” method, have a look at the demo here(by clicking on the “Log State” button, you will see the current tasks in the console)

If you have any other questions, please do not hesitate to contact us again!
Best Regards,
Ivan Peevski
