  • Expiration days – Number of days after those each listing created under this category will expire.
    Default is 0, which means no expiration. Set i.e. to 30, if you want listings in this category expire after 30 days from publishing.
  • Enable / Disable the price field – price can be disabled for categories like Jobs or Relationship. When price is disabled, price field should not be available while publishing listing (on publish/edit page) as well as on item page and item cards on search or home page. This may depend on theme you are using as well.
  • Description – category description or details that can be shown on search page, when this category is selected. This field is shown by themes just rarely.
  • Icon – icon for this category, strongly depends on theme used. It may or may not be used at all, theme can use own functionality for that. Icon can be simply string, keyword, class of Font Awesome icon, file name of image or URL. It only depends on theme you are using.
  • Color – in same way as icon, color field strongly depends on theme you are using. Theme may not be using this field at all. It is expected to enter here color code like HEX, i.e. #1e1e1e.
