It is possible to display ‘Add to Cart’ buttons when viewing a list of products within a category.

To enable this for your ENTIRE store, do the following:
- Click the ‘Advanced’ button in the left sidebar and select ‘Stores’. Then select ‘Configuration’.
- Click on ‘App Settings’ in the left side bar and then select ‘Options’.
- You should see an option there called ‘Include Cart Button on Listing’.
- Set this to ‘Yes’.
- Click ‘Save’.

This will activate the feature for EVERY category.
If you want this just to be on specific categories then do the following:
- Go to ‘Catalog’ in the left sidebar and select ‘Categories’.
- Click on the category in the tree you wish to show cart buttons on.
- Click on the ‘Content’ heading to expand it.
- Under where it says ‘Include Cart Button on Listing, de-select where it says ‘Use Config Settings’.
- Then tap the switch to set it to ‘Yes’.
- Click ‘Save’.
