Customizing the Free Gift Selection rendering


Overview of the Free Gift rendering Scriban template, which you can customize by modifying the code.

The Free Gift Selection rendering includes a rendering variant in the form of a Scriban template. The Free Gift Selection rendering has its own default rendering variant root and default rendering variant (/sitecore/Content/<tenant>/<site>/Presentation/Rendering Variants/Free Gift Selection), which uses a Scriban template for generating the markup and an AJAX call to the CD to trigger the Add-to-cart event when the Claim gifts button is clicked. Free gifts are added to the cart lines using the API and the IsFreeGift property is set to true.

While you can modify the Scriban template, it is best to create a new custom rendering variant in this case so that the customization does not get overridden during software upgrades. You can also change the labels for the rendering.

The following code shows the Scriban template for the Free Gift Selection rendering defined within the default rendering variant. The list of sellable items from which a shopper can select their free gifts is passed to the Scriban template using the embedded item o_model.

The following sequence diagram shows a high-level view of the calls made when the shopper selects and claims their free gifts. Only one call is used to retrieve the latest cart details so that the Free Gift selection rendering is automatically updated whenever the shopper makes changes.
