(example?) Mobile Accordion Menu footer on Editor X Mobile Site?

Q: Best way to recreate accordion menu for mobile view, like on the editor X site (ideally without Velo)

Essentially I have a desktop/tablet footer menu section like this, which I’d like to convert into an accordion on the mobile view.

Hence checking best practices/approach or example project template to reference?
Thanks in advance!

Mobile Example references

Alternate Mobile View

Grateful if anyone point me in the right direction of an example project. Thanks again!
