The first thing to do is to set up your e-merch parameters. This section presents the list of attributes provided by your product feed and enables you to activate the one you want as filters, or to be able to use in Boosters/Strategies, and Spotlights/Showcases.
We strongly recommend renaming any additional attribute with your own label so you can easily find them again in the platform and mainly because this label is the one that can be displayed to your users (filter for instance).
Note that you can preview and search values within an attribute by clicking the + icon.
