This is a great module for a wholesale store (but can be used for any store). It will display products with 1, 2 or 3 attribute groups as a grid.
It lets the customers quickly add multiple product combinations with 1 click, and see all the prices.
You can also use radio button to quickly select a combination without entering a quantity.
You can control the order of groups (horizontal or vertical) and the order of the attribute items.
You can display a color or texture (image) next to each attribute item.
You can display the grid on the page or in a popup.
You can add an additional attribute group, which will use a drop down menu.
It lets you copy attributes from one product to another, or to a category (to all the products in it).
