The module allows to create combinations of related product option values, set specific attributes/settings per combination and limit customers to select only available combinations of option values (on the product page in the customer section).
It is useful for sales of products, having interlinked (related) options (such as size and color of clothes for example).

Main features of the module:

• combine any number of product option values ( types "Select" and "Radio")
  
• set custom settings/attributes per combination of related options (Price, Quantity, Model, SKU, etc.)
  
• control stock per combination of related options (subtract, 'hide out of stock' combinations, etc.)
  
• limit customers to select only available combinations of related options
  
• provide different styles of viewing the limitations (disable or hide irrelevant values, select step-by-step)
  
• select default combinations of related options
  
• update the product code (model) depending on selected combination of related options
  
• its own simple export/import (to export/import combinations of related options)
  

If you need to use more than one variant of option combinations per product you can use the PRO-version of the module Related Options PRO 3
