Product page widgets

Frequently bought together

PDP

The Classic FBT widget pairs the current product with complementary items in a single checklist the shopper can add in one click — with an optional automatic discount on every bundle item. The shopper ticks the items they want, the live total updates, and one button adds everything still selected.

Layout

Classic FBT

Selectable

Vertical checklist of the current product (labelled This item) and the bundle products. All items are pre-checked; each row has its own variant picker. The total updates as boxes are toggled and one button adds every selected item to the cart.

Shopper controls the bundle composition — no forced adds.
Live total updates as boxes are toggled.
The discount applies to each selected item, so the saving always matches what's in the cart.
Works well in narrow columns and on mobile.

Best for: Add-ons and accessories where each item has its own price tag — and where 'pick the ones you want' converts better than 'take the full kit'.

How to create an FBT campaign

In the Summer Upsell admin

1 In the Summer Upsell admin, click Create Campaign.
2 Under Frequently Bought Together on the Product Page list, pick Classic FBT.
3 Give it an Offer name (e.g. FBT — Coffee starter kit).
4 Set the Trigger — typically Specific products for the hero product, or Specific collections if many products share the same bundle.
5 Pick the Product source. Specific products works best for FBT because the bundle should feel curated.
6 Add the bundle products.
7 Optional: tick Enable bundle discount, set a Display Title (e.g. Bundle save), Percentage or Fixed Amount, and the value.
8 On the Design tab, set the Widget Title (e.g. Frequently bought together), Button Text, and pick a template.
9 Click Publish. The Test campaign in store checklist runs (campaign active, products available, app embed enabled, widget block added) — fix anything red, then click Publish campaign.

In the Shopify theme editor

1 Open Online Store → Themes → Customize.
2 Switch to the Products → Default product template.
3 Click Add block below the buy buttons or the product description.
4 Pick ✨ Summer: FBT Bundle from the Apps section.
5 Drag to position (most stores place it right below the buy button or after the description).
6 Click Save.

Field	Type	Description
Offer name	Text	Internal label only — used to find the campaign in the admin. Customers never see it.
Trigger	Radio	All products, Specific products (default) or Specific collections. Decides where the widget is eligible to render. Cart widgets use Any cart and Post-Purchase uses Any order instead of All products.
Trigger products / collections	Picker	Shown for the Specific options. Pick the products or collections that should fire the widget.
Product source	Radio	Specific products, Automated recommendations or Summer AI powered by ChatGPT (credit-based; every plan includes credits). See Upsell sources.
Offer products	Picker	Shown when Specific products is selected — click Add Products and pick the products the widget will recommend.
Discounts	Dropdown	No discount, Use Summer Upsell discount functions (Recommended), Use discounts that are dynamically created or Use an already existing discount code. See Discounts for how each mode works.
Type / Value	Dropdown + number	Product discount (each offer item) or Order discount (the whole order), and the amount as % or a fixed amount in your store currency.
Discount code	Text	Optional for Summer discount functions (creates a code-based discount the widget applies automatically); required for existing discount code.
Combination	Checkboxes	Whether the discount can combine with product, order and shipping discounts.

Design tab

Every campaign opens on the Offer tab. The Design tab next to it controls how the widget looks on the storefront. The same set of controls is reused across nearly every widget type, so once you learn it on one campaign the rest are familiar. A live preview on the right updates as you change settings — switch it between desktop, mobile and full size.

Field	Type	Description
Layout	Dropdown	Shown on widgets that have more than one layout (Cross-sell, Upsell, In-Cart Upsell, Product Add-on). Switches the layout without recreating the campaign.
Widget Title / Button Text	Text	Heading shown above the widget and the label on its Add buttons. For Classic FBT, Bundle, Popup, In-Cart Upsell, Cart Popup and Post-Purchase you set them here; for Upsell, Cross-sell, FBT Full Width and Product Add-on they live on the Language tab (default language block).
Subtitle	Text	Optional line under the title (e.g. Customers also bought these).
Templates	Visual picker	27 ready-made themes: Modern Clean, Ink → Slate, Slate → Ocean, Espresso → Sunset, Blossom → Crimson, Teal → Ocean, Forest → Teal, Ocean → Glacier, Sunset → Crimson, Lilac → Denim, Cherry Blossom, Piggy Pink, Fresh Mint, Baby Blue, Sand, Lavender, Honey → Amber, Vanilla → Cream, Royal → Violet, Sunset Orange, Moonlit Asteroid, Amin, Celestial, Witching Hour, Frost, Quepal and Sublime Light. Picking a template sets the button style, card border and every color below at once — then fine-tune anything you want.
Background (optional)	Toggle + color	Give the widget its own background color instead of inheriting the page background.
Border Radius	Dropdown	Sharp (Square) or Curvy (Rounded) corners on cards and buttons.
Image Fit	Dropdown	Cover (crop to fill), Contain (fit inside, may show whitespace), Fill (stretch to fit).
Font family	Dropdown	Your Theme Font (inherits from your theme), Inter, Roboto, Montserrat, Poppins, Playfair Display, Libre Baskerville, Oswald, Plus Jakarta Sans.
Typography sizes	Number (px)	Title weight, Button font size, and individual sizes for Product Title, Price and Compare price. Set the compare size smaller than the price size for a clean strike-through look.
Colors	Color picker	Primary color, Product Title color, Price color and Compare price color. Override any single value after picking a template.

Tip: Click any template to seed every color at once, then nudge the individual swatches. Faster than building a palette from scratch.

Language tab

The Language tab holds the storefront copy for the widget. The Default language block is always there; click Add another language to add any locale your Shopify store has published and translate the title, button text and other storefront strings for it. Default text is pre-filled in English, Spanish, French, Arabic, Turkish and German. A locale you don't add falls back to the default language.

Discount logic

The bundle discount is a Shopify automatic discount that applies to every bundle item the shopper adds through the widget, the current product included. Unticked items are simply not added; ticked items keep their discount at checkout.
