The Product Specifications app provides blocks to render product specification information.

In your theme manifest.json, add the Product Specification app as a dependency:

Now, you can use all the blocks exported by the product-specifications app. See the full list below:

Block name	Description
product-specification-group	Renders the product specification group.
product-specification	Renders the product specification. It should be declared as a child of product-specification-group.
product-specification-value	Renders the product specification value. It should be declared as a child of product-specification. It can be rendered with HTML.
product-specification-text	Mandatory children of product-specification-group, product-specification, and product-specification-value. Depending on which block is declared, the product-specification-text renders information regarding a specification group, a specification, or a specification value.

Copy the example below and paste it in the desired theme template, modifying it as necessary for your use case. If necessary, add the product-specification-group block to the template block list.

The Product Specification blocks need a Product context to work properly because they handle product information. Therefore, when declaring them, be sure that they are in a theme template in which this context is available, such as store.product.

You can also use other blocks to wrap the blocks provided by the Product Specifications app, such as the ones exported by the Flex Layout app. For example:

Prop name	Type	Description	Default value
filter	object	Filters the specifications that the block should display.	undefined

• filter object:

Prop name	Type	Description	Default value
specificationGroups	[string]	Array of specification group names to be hidden or shown (depending on what is defined in the type property) by the product-specification-group block.	undefined
type	enum	Determines whether the specification group names passed to the specificationGroups prop should be displayed or hidden on the UI. Possible values are: hide (hides specification groups declared in the specificationGroups prop) or show (only shows the specification groups declared in the specificationGroups prop).	undefined

product-specification-text props

Prop name	Type	Description	Default value
blockClass	string	Block ID of your choice to be used in CSS customizations.	undefined
message	string	Defines the block default text message to be rendered on the UI. You can also define the text message a block will render on the UI using the Site Editor in the Admin and the markers prop.	undefined
markers	[string]	IDs of your choice to identify the block's rendered text message and customize it using the Site Editor in the Admin. Learn how to use them by reading the documentation on Using the Markers prop to customize a block message. Note that a block message can also be customized in the Store Theme source code using the message prop.	[]

As stated in the previous step, the product-specification-text uses the ICU Message Format, making it possible to fully edit the block's rendered text messages.

When using the message prop, you will not need to create an advanced configuration: declare the prop directly in your Store Theme app and pass to it the desired text value to be rendered with the block.

The markers prop, in turn, requires you to add an extra configuration in the Site Editor of the Admin to properly work. When using this prop, do not forget to check out the block message variables (shown in the table below) and the Using the Markers prop to customize a block's message documentation.

Message variable	Type	Description
groupName	string	Specification group name.
specificationName	string	Specification name.
specificationValue	string	Specification value.
isFirstSpecificationValue	boolean	Determines whether it is the first specification value (true) or not (false).
isLastSpecificationValue	boolean	Determines whether it is the last specification value (true) or not (false).

To apply CSS customizations in this and other blocks, follow the instructions given in the recipe on Using CSS handles for store customization.
