Aligning container vertically

I have filter buttons on my website, and would like them to be aligned vertically on the left hand side of my page (2 per line, in that column). Currently my container and buttons are aligned horizontally and its obviously not working.

Could you advise how to fix this? I know it must be an easy fix but I just can’t seem to find the solution.

Here is my site Read-Only:

@bkmat take a look at this.

Thanks so much @guoshuzhang, the video was very helpful. Follow-up question: if I wanted to have two on the same row, how should I go about this?

Thanks again

@bkmat try use grid

another way use wrap
