Joomshopping Administration: Product edit list plus

This addon extends the batch product editing feature in the JoomShopping admin area.
It adds advanced control over how categories and characteristics are modified during bulk updates.

You can now choose how to apply changes using one of three actions:

Modes:

• Add – adds selected categories or characteristics without removing existing ones
  Example: Product has category Auto. If you add Moto, the product will have both Auto and Moto.
• Overwrite – replaces existing categories or characteristics with the selected ones
  Example: Product had Auto. If you overwrite with Moto, it will only belong to Moto.
• Delete – removes only the selected categories or characteristics
  Example: If you delete Moto, the product will be removed from Moto but stay in other categories like Auto.

If the lib-checkboxblock library is installed,
the category and characteristic multiselects will be enhanced with a fast search field.
This allows you to quickly find items by name, making batch editing even easier.
