Troubleshooting Supply

Can I make my gallery wider?

The Supply gallery page has a unique, vertically-stacked design. You can decrease the size of the images by increasing the spacing around them. However, you can’t adjust the width of the gallery image column.

To create a gallery with a different style, add a layout page and then use a gallery block.

I'm seeing a gray overlay on my product images

This happens for images with transparent backgrounds in Store Pages with the Viewbook, Showroom, and Flipcard layouts.

If you don't like the way it looks, either add product images with non-transparent backgrounds, or choose Product list style: catalog in the Products section of style styles.

My homepage is wider than other pages

In Supply, you can set a layout page homepage to display at full width. If you don't like the way this looks:

  1. In the Home menu, click Design, and then click Site styles.
  2. Scroll down to the Homepage section and uncheck Full width homepage.
  3. Click Save.

Where did my sidebar go?

Supply features a navigation sidebar on all pages. Due to responsive design, when your browser window is narrow, the sidebar content moves to the top of the page as a navigation mobile bar.

Widen the browser window and the sidebar will reappear.
