You may like your customers to choose their quantity right on the Product page. Instead of limiting them to adding one item at a time and then having to adjust this amount on the basket page with a dropdown.
You can also change the quantity drop down on the basket page to a text input.
- Firstly log into your Dashboard and go to the Dashboard -> Manage Store -> Store Preferences
- Scroll to the section "Add to basket with quantity"
- Set the option to "Show Quantity Selector", this will save the setting automatically.
- View your Product page to make sure this works as expected.
