Hello,

01.There is no such option in Theme Settings to remove a particular category from the shop page grid because the categories are generated by WooCommerce in the shop grid and our theme doesn’t influence. Navigate to Theme Settings > Product Archive > Products Styles > disable the option product categories.

02. To achieve this, you can create custom pages and use the Product Grid or Carousel widget in WPBakery or Elementor. Simply choose the appropriate data source (e.g., Featured, Top Rated, or Sale Products) for each section. Then, link these pages to your header for easy navigation.

03. You can add the filters from Appearance > Widgets > Add the filters in the shop page widget area.
Follow this guide and setup the sidebar: https://xtemos.com/docs-topic/widgets-and-sidebars/
