Using the Swift Galleries Designer
This one's easier to just show you in a video, so here you go. If you want to skip straight to learning how to save a suggestion, I've typed out the steps below this video.
Saving a Suggestion
After you have placed products on the wall, either via templates or adding new products, you can add photos to the products on the wall if you want first, or leave them as empty products. Then click on "Add to Suggestions":

Note:
We strongly recommend that you have at least one suggestion saved before creating an online or in-person sales opportunity. This is also the only way to complete this step during your trial and move on to the next step.
