I would like to setup a sidebar navigation that is sticky when I scroll and hides in mobile view (with a hamburger nav in the corner). This Soledad demo exhibits what I am going for (https://soledad.pencidesign.net/soledad-vertical-nav/page/3/?demo=mixed-2&sidebar=right) but I can't seem to find any instructions on how to achieve this in the instruction materials? Could someone please provide instructions or a walkthrough on how to achieve this? Thanks!
