With YITH Multi Vendor you can turn your e-commerce store into a marketplace (a multi-vendor platform) like Amazon or Etsy.
If used with YITH Surveys, also your vendors can create their own surveys and show them on their product pages.
To use this option, make sure both plugins are installed and activated. Then, enable the Survey module from YITH > Multi Vendor > Modules.
Now, your vendors will be able to create their own surveys.
Please, consider, however, that the surveys can only be displayed on the product page (no checkout option available for vendors).
For more details about YITH WooCommerce Multi Vendor, please refer to the plugin documentation.
