Hello,
1. To change the font size of the categories in sidebar use this code in custom.css file:
.product-categories > li > a {
font-size: 13px;
}
2. To disable categories showing on the Shop page go to Woocommerce > Settings > Products tab and select “Show products” in the “Shop Page Display” field.
3. Unfortunately there is no such feature in our theme. Sorry. You may contact Woocommerce support. Perhaps they will suggest you some solution.
Regards,
Eva Kemp.
