Add card expandable to framework7 v3


I would like to know how I can add card-expandle to a project built on Framework7 version 3.
I tried to add the card component(JS and CSS files) from Framework7 v4 to my project. The CSS seems to work but not JS.

Thank you.

You can not, the card-expandle have integration with F7 core(events, logic and else)

Thank you Overman for your response.

Что вам мешает перейти на v4?

I have not yet read all the new notes about v4 and its affect on my code.
