#Layouts

Available layouts differ by bundle type. You choose the layout when you create or edit a bundle, not in the customizer.

LayoutBest for

CompactTight spaces or sidebar placement

Grid and Slider cards have a taller image area, which works well for product photography.

#Style presets

Eight one-click presets give you a starting point:

  • Minimal: Sharp edges, no shadows, high contrast
  • Soft: Rounded corners, subtle shadows
  • Bold: Strong contrast, fully rounded, heavy shadows
  • Elegant: Sophisticated curves and spacing
  • Dark: Dark background with cyan accents
  • Nature: Green tones, organic feel
  • Warm: Orange and amber palette
  • Professional: Blue accents, structured, clean

Selecting a preset applies all its values at once. You can then override individual settings without losing the rest of the preset.

#Color and shape controls

In the Colors section, you control:

  • Accent color: Buttons, badges, and interactive elements
  • Text color: Headings, product names, body text
  • Background color: The widget container background
  • Border color: Borders and dividers
  • Savings color: The color used for discount text and the savings highlight

The Colours switch at the top of the Colors section (Custom or Follow theme) sets whether these colors come from you or from your theme. It applies to every bundle type. Follow theme takes text, background and button colours from your theme, including dark mode; your savings colour is kept.

In the Widget box section, Corner roundness (Sharp / Modern / Rounded) and Shadow depth (None / Soft / Strong) set the shape. Spacing sets the padding density (Compact / Comfortable / Spacious).

#Responsive overrides

Layout and spacing settings support separate values for desktop, tablet, and mobile. For example, you can set Grid to 3 columns on desktop, 2 on tablet, and 1 on mobile. Fields with responsive support show small device icons. Click an icon to set a device-specific value.

Color settings and corner/shape style apply uniformly across all screen sizes.

#Saving

Changes aren't applied until you save. A save bar appears at the bottom of the customizer when you have unsaved changes. Save pushes the styles to Shopify metafields and they take effect on the storefront immediately. Discard reverts to the last saved state.
