How to show the sidebar as a button on mobile ? (Flex Theme)

[paul_fouche]

Hi,

I would like to show my sidebar with filters as a button on mobile, like Kapten & Son is doing here: https://kapten-son.com/de/rucks%C3%A4cke

You can see that the filters are shown as a button on mobile. Is there a simple way to do it?

Here is my page with the filters: https://fitzandhuxley.myshopify.com/collections/all

I use the Flex Theme by Out Of The Sandbox.

Thank you in advance,

Paul
