There are three ways to add, replace and remove products in a catalog: from the designer, from the organizer on the side, and straight from your inventory. The first two are best for one product at a time. The inventory is the fastest way to add many products at once. The video shows all three, and each step below links to its chapter.
A catalog already created in Foldsquare.
On the page, select a product block and click Add product. Select the product you want and it is added to your catalog.
Select the product block, click Replace, and search for the item you want instead.
Select the product block and click Remove.
The organizer on the side lists every product in your catalog, grouped by category. To add a product, find an empty area, click an empty block, and search for your item. Once selected, it is added to the catalog.
Click Replace and select the new product to swap it in. Removing a product from the organizer works the same way.
The inventory shows your collections, pulled from your store data. You have two options:
Drag a product from the inventory and drop it onto an existing product. The new product takes its place.
