Electro is a WooCommerce theme and it supports all the features of WooCommerce. However “Vendor Management” is not a feature of WooCommerce. There are plugins like Dokan, WC Vendors, etc that allow you to extend WooCommerce into a vendor management system. While the theme is compatible with Dokan and WC Vendors, we only provide basic compatibility support. We do not provide support for its features or non-availability of features.
