Hierarchy Grid
One large lead image across the full width of the gallery, with the rest of your photos in a grid below it. The main shot gets the spotlight; the details follow.
Hierarchy Grid is a grid with a clear first image. Your featured photo spans the whole width, then the remaining photos fill a grid of columns underneath — two by default. Like every grid layout, nothing slides and every photo is visible.
The free plugin doesn't include this layout; it ships Thumbs Bottom and Thumbs Top.

When to choose it
- You have one hero shot and several detail shots. The lead image sells the product; the grid answers "what does the sole look like?"
- You like the openness of a grid but want an obvious starting point. Plain Tiles treats every photo the same. Hierarchy Grid tells shoppers where to look first.
How to switch to it
- Go to FluentCart → Product Gallery → General.
- Under Gallery Layout, click Hierarchy Grid.
- Click Save Settings.

Things worth knowing
- The lead image is always the first photo — the product's featured image in FluentCart. To change which photo leads, change the featured image on the product.
- It adapts to smaller screens. Below about 990px wide the grid drops to two columns with the lead image still full width; on phones (below about 520px) everything stacks in a single column.
- The product summary stays in view beside the gallery on screens wider than about 770px.
