How to create ratings field in In-Depth reviews?

If you have In-depth fields set to “Yes” (in the “Fields” area of the “Options” tab), you can add multiple fields for reviews using Review Item. You can just click on the Add button in the Fields section under the Options Tab and then select ReviewItem in the drop-down. Once you fill in the other details like the Name of the reviewItem, you can click on Save and repeat to add as many review Items as you want.
