Interactions flow for a filtering system

In 2020 I will commit to posting my work-in-progress more often.

This is something I'm working on at askdata.
It's a way to filter the column of table.
Once the user clicks, he can see the data type (ID/KEY in that example) the dataset where this come from, and the field to filter.

Let me know if you have feedback, and thanks for passing by!

If you are interested in product design, I will add more on my profile, so please follow my adventure.
