create a left-off-canvas-toggle for layered navigation on category page in magento 2

I want you to create a category-view page, which works like: [login to view URL] The Filter button opens the layered navigation on the left side on click. If the sidebar is not open, the elements are moving to fill out full page. I want exact this „masonry effect“ on my magento shop. Currently using this theme: [login to view URL] which has already a similar function, but it's on top and not left side. The theme has a left side navigation, but it stays always fixed. PLEASE FIND ATTACHED IMAGES So what to do: 1. create a fullwidth view with current design (given by theme) of product thumbnails and buttons to interact (add to cart, quickview, title, etc.) 2. create the off-canvas effect of layered navigation on click on filter
