Go to Products > Categories (any level) > WeltPixel Options
Link - if necessary you can set a custom link for any category in the menu, including external links.
Open in new tab - opens the custom link/category page in new tab
Note:
If you are using the option to add custom links in the Mega Menu we recommend to also use Google XML Sitemap Extension and exclude categories from sitemap that are only used for menu links and are not real categories. Applicability: You may want to add a category that links to an external website, directly to a product page, etc..
