Seller Management
Marketplace sellers can autonomously manage their own size standards, create body measurement instructions, and build size chart matrices directly from the Marketplace Seller Dashboard.
Accessing the Seller Size Chart Menus
When a registered marketplace seller logs into their frontend customer account, a dedicated Marketplace Size Chart section appears in their navigation sidebar:
Seller Group Module Support
If the Webkul Marketplace Seller Group module is installed, store administrators can control which seller tiers or groups have permission to create and manage size charts via action-level ACL permissions.

4. Seller Data Isolation
All entities created by a seller are strictly isolated using their Magento customer ID:
- Sellers only view their own units, measurements, and templates.
- Attempts by other vendors to view or modify an unauthorized entity ID are automatically rejected.
- When creating or editing products, sellers only see their own active size chart templates in the product assignment dropdown.
