Admin users very frequently need to change a product dropdown attribute to a multiselect in Magento. By default, Magento doesn't allow this feature via Admin Panel. So when admin users have created some product attributes, there's no way to change the type of the attribute after saving.
With our extension, users get a possibility to change everything at any moment! Now, you can change the type of all attributes and your data will be seamlessly migrated from one type to another, keeping excellent consistency. Drop-down "Catalog Input Type for Store Owner" on product attribute page will be unlocked forever!

• Easy to setup and configure

• Ability to change attribute type for already existing product attributes
