Element attribute API

If you prefer to use your own elements, you can add Fontdue interactivity to them by adding custom fontdue-* attributes. They will become interactive after the Fontdue.js scripts are loaded.

Example: Cart Button

Create your own cart button that opens the Store Modal by adding the fontdue-click="open-store-modal" attribute. The example below includes the optional fontdue-store-route attribute which always opens to the Cart page, even if itโ€™s empty.

<button 
  type="button" 
  fontdue-click="open-store-modal" 
  fontdue-store-route="cart">
  Cart
</button>
๐Ÿ“–
Note: The <fontdue-cart-button> is aware of how many items are in the cart, and will prevent navigating to the modalโ€™s cart page if there are no cart items, but this behavior isnโ€™t implemented on the fontdue-store-route attribute.

Example: Buy Button

Create a buy button which opens the modal at a particular product page:

<button 
  type="button" 
  fontdue-click="open-store-modal" 
  fontdue-store-route="product/{{ collection_id }}">
  Buy
</button>

The Collection ID can be found in the Fontdue admin panel, on the Font collectionโ€™s Widget codes tab, or through the GraphQL API.

Extend this functionality to select a particular product with the fontdue-store-select attribute:

<button 
  type="button" 
  fontdue-click="open-store-modal" 
  fontdue-store-route="product/{{ collection_id }}"
  fontdue-store-select="{{ sku_id }}">
  Buy
</button>

You can find SKU IDs in the Fontdue admin panel. A SKU can be attached to various products including Collections, Bundles and Font styles. For collections, find it on the Widget codes tab. For individual font styles as well as bundles, find it under the Price field. A product must have a price to get a SKU ID and be selectable.
