How to keep added list in localSrorage after page refresh?

Question

JavaScript

Good afternoon!
Help, please, deal with the issue.
I do this: https://jsfiddle.net/nlynx/74eo9a2g/3/

Here you can drag tasks into different blocks and add new tasks.
It is necessary that at least when the page is refreshed, the current working state remains unchanged, and not reset to default.

Thank you in advance.

localStorage.setItem('items', JSON.stringify(this.items)); // записать
this.items = JSON.parse(localStorage.getItem('items')) || []; // получить
