Hello,

Sorry to say but unfortunately right now under the Theme Settings, there isn’t any option available to make the default Sidebar on the Shop page sticky. We have tried with a CSS solution too but that didn’t work out well either.

If you want you can try out the following Custom CSS if this works out for you:

.sidebar-container .widget-area {
   position: fixed !important;
}

Location to paste Custom CSS, go to Dashboard >> Theme Settings >> Custom CSS >> Global CSS section >> paste the CSS.

Best Regards
