Dear Kennylo,
1. By default, our online shop has no such functionalities. So, it required customization.
2. You can follow the path below:
Dashboard-> Pages-> All Pages
Click on the relevant page to edit the contents in it. You can edit its icon on the right side.
3. By default, neither our theme “Online Shop” nor WooCommerce provides such type of functionalities. So, you have to go for plugin .e.g Woocommerce
role
based price plugin.
4. On our inspection, we saw that category item and sub-category item displayed their products under HOME / PRODUCTS / CATEGORY or SUB-CATEGORY.
Best Regards!
