Understanding the Dropdown Column

Hi
I’ve been looking everywhere and can’t find a solution

We are trying to work with a dropdown column and to sort it in different views. We can not convert it to a status column since it has more than 40 labels, and it’s growing slowly.

The best thing will be if we could create a Kanban out of it, and see a list of items under each label.

Is there any way to sort this thing out?

Thank you very much
