Product Specifications

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

{"base64":"  ","img":{"width":780,"height":318,"type":"png","mime":"image/png","wUnits":"px","hUnits":"px","length":19580,"url":""}}


Step 1 - Adding the Product Specifications app to your theme's dependencies

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

"dependencies": { "vtex.product-specifications": "1.x" }

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

Block nameDescription
product-specification-groupRenders the product specification group.
product-specificationRenders the product specification. It should be declared as a children of product-specification-group.
product-specification-valueRenders the product specification value. It should be declared as a children of product-specification. It is possible to render with HTML.
product-specification-textMandatory children of product-specification-group, product-specification and product-specification-value. Depending on which block it is declared, the product-specification-text renders data regarding a specification group, a specification, or a specification value.

Step 2 - Adding the Product Specifications' blocks to your theme's templates

Copy the example stated below and paste it into your theme's desired template, making the necessary changes according to your desire. Remember to add the product-specification-group block to the template's block list if needed.

{ "product-specification-group": { "children": ["product-specification-text#group", "product-specification"] }, "product-specification": { "children": [ "product-specification-text#specification", "product-specification-values" ] }, "product-specification-values": { "children": ["product-specification-text#value"] }, "product-specification-text#group": { "props": { "message": "{groupName}" } }, "product-specification-text#specification": { "props": { "message": "{specificationName}" } }, "product-specification-text#value": { "props": { "message": "{specificationValue}" } } }

Notice that the Product Specifications' blocks necessarily need a Product context in order to work properly since they handle product data. Therefore, when declaring them, be sure that they are in a theme template in which this context is available, such as the store.product.

You also can 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:

{ "product-specification-group#table": { "children": ["flex-layout.row#spec-group"] }, "flex-layout.row#spec-group": { "props": { "blockClass": "productSpecificationGroup" }, "children": ["flex-layout.col#spec-group"] }, "flex-layout.col#spec-group": { "children": ["flex-layout.row#spec-group-name", "product-specification"] }, "flex-layout.row#spec-group-name": { "props": { "blockClass": "productSpecificationGroupName" }, "children": ["product-specification-text#group"] }, "product-specification": { "children": ["flex-layout.row#spec-item"] }, "flex-layout.row#spec-item": { "props": { "blockClass": "productSpecification" }, "children": ["flex-layout.col#spec-name", "flex-layout.col#spec-value"] }, "flex-layout.col#spec-name": { "props": { "blockClass": "productSpecificationName", "width": { "mobile": "50%", "desktop": "25%" } }, "children": ["product-specification-text#specification"] }, "flex-layout.col#spec-value": { "props": { "blockClass": "productSpecificationValue" }, "children": ["product-specification-values"] }, "product-specification-values": { "children": ["product-specification-text#value"] }, "product-specification-text#group": { "props": { "message": "{groupName}" } }, "product-specification-text#specification": { "props": { "message": "{specificationName}" } }, "product-specification-text#value": { "props": { "message": "{specificationValue}" } } }

product-specification-group props

Prop nameTypeDescriptionDefault value
filterobjectFilters the specifications that should be displayed by the block.undefined
  • filter object:
Prop nameTypeDescriptionDefault value
specificationGroups[string]Array of specification group names to be hidden or shown (according to what is defined in the type property) by the product-specification-group block.undefined
typeenumWhether 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 nameTypeDescriptionDefault value
blockClassstringBlock ID of your choosing to be used in CSS customization.undefined
messagestringDefines the block's default text message to be rendered on the UI. You can also define which text message a block will render on the UI using the admin's Site Editor and the markers prop.undefined
markers[string]IDs of your choosing to identify the block's rendered text message and customize it using the admin's Site Editor. Learn how to use them accessing the documentation on Using the Markers prop to customize a block's message. Notice the following: a block's message can also be customized in the Store Theme source code using the message prop.[]

Step 3 - Editing the product-specification-text's messages

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 won't need to perform any advanced configurations: declare the prop directly in your Store Theme app, passing to it the desired text value to be rendered with the block.

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

Message variableTypeDescription
groupNamestringSpecification group name.
specificationNamestringSpeficiation name.
specificationValuestringSpecification value.
isFirstSpecificationValuebooleanWhether it is the first specification value (true) or not (false).
isLastSpecificationValuebooleanWhether it is the last specification value (true) or not (false).
