Quick answer
KitForge bundle widgets on product pages require the auto bundle card app embed. Enable it once per theme in Online Store → Customize → App embeds, then save.
- App embeds are per-theme — duplicate themes need the embed re-enabled.
- This is separate from installing the KitForge app.
- Manual blocks are optional; the embed is the default auto-mount path.
- Save the theme after toggling or changes will not appear live.
Why Shopify requires an app embed
Theme app extensions cannot modify every template automatically. The body-targeted app embed is Shopify's supported way to inject KitForge on all product pages without editing Liquid.
KitForge onboarding treats this as step one because bundles cannot merchandize on the storefront until the mount point exists.
Enable the embed in under two minutes
From Themes, click Customize. In the left panel, open App embeds (puzzle-piece icon). Find KitForge auto bundle card and switch it on. Click Save.
If you use multiple themes (e.g., staging), repeat for each theme you test bundles on.
Verify it worked
On any product page, view page source and search for data-kitforge-offers-root. Or open KitForge admin — the inactive embed banner should disappear.
Final recommendation
Enabling the KitForge app embed is the fastest fix for invisible bundle widgets. Do it before building your first campaign.
If you want this kind of offer to feel native to the buying journey, Kitforge Bundles is built around that exact problem: turning related Shopify products into clearer bundle offers before the shopper reaches checkout.
FAQ
Do I need a developer to enable the embed?
No. Any staff with theme customization permission can toggle app embeds.
Can I use blocks instead of the embed?
Yes. Add KitForge section blocks to specific templates and set widget position to manual_app_block. The embed is still recommended for store-wide coverage.
