Hello,
Theme does not have option to have individual widget area for every category you have. Only description area, but you can’t use widgets there. Anyway WC plugin does not display filters widgets for the category if this category does not have product with this attribute. For example https://www.8theme.com/demo/xstore/wedding/product-category/bouquets/ and https://www.8theme.com/demo/xstore/wedding/product-category/man/ Flowers do not have size attribute but have color http://prntscr.com/hemgj4 and products from man category do not have color but have size http://prntscr.com/hemh6r At the same time filter area includes both filters http://prntscr.com/hemhlc
Regards
