In addition to the basic options we have covered so far, Odoo offers several advanced options that give you more control over how products appear on the store. These options include specifying multiple categories, alternative products, and accessories, as well as direct control over the position of the item on the store.
Once again, you will need to go to the Products page and observe that we have specified a few advanced options:
In the preceding screenshot, instead of our product now showing up inside of one category, it will show up in the T-shirts, School, and 2018 categories. This gives us more flexibility when we're designing our eCommerce store.
To see the categories on your website, you will need to go under the Customize tab on the store page and check the Product Categories option.
