I am attempting to build an online store for a restaurant that would like to process online orders. GHL allows me to create a entree product, but I am unable to convert the entree to a combo. For example, the combo offers 2 sides with the entree, but I am unable to add the sides as variants, so I have to create multiple combo products so that customers have all the options. This is very time consuming and creates overcrowding in the store. Guests should have the ability to select the entree and add the sides for a combo. If this already exists, please advise where instructions can be located. If it does not, please add the option ASAP.
