Building a carousel using Slider Layout

Some block types in Store Framework carry and provide data to their child blocks instead of rendering storefront components.

These blocks are instances of a list-context interface called lists. They are exported by the vtex.list-context app.

A carousel is essentially a slider that showcases a collection of images. Hence, to create a carousel for your store, you can use one of the available list-context instances together with a slider-layout, a versatile layout block that allows you to create a Slider component from a set of other blocks.

Check the instructions below for more information.

Instructions

Make sure your store is running vtex.store@2.70.0 or higher.
Add the following dependencies to the theme manifest.json file:


_10"vtex.store-image": "0.x",
_10"vtex.slider-layout": "0.x"

Declare the list-context.image-list block and use the slider-layout as its only child. Each desired image should be forwarded to the list-context.image-list as an object with the following properties:

Property	Type	Description	Default value
`image`	`string`	Link to the image.	N/A
`mobileImage`	`string`	Link to the mobile image.	N/A
`description`	`string`	The image description.	N/A
`link`	`link`	Specifies the link the image will redirect to when clicked.	N/A

Example:


_16"list-context.image-list#demo": {
_16    "children": ["slider-layout#demo-images"],
_16    "props": {
_16      "height": 650,
_16      "images": [
_16        {
_16          "image": "https://storecomponents.vteximg.com.br/files/banner-infocard2.png",
_16          "description": "something something"
_16        },
_16        {
_16          "image": "https://storecomponents.vteximg.com.br/assets/vtex.file-manager-graphql/images/Group%207%20(1)%20(1)%20(1)%20(1)%20(1)___c6b3ed853fb16a08b265753b50e0c57a.png",
_16          "description": "something something"
_16        }
_16      ]
_16    }
_16  },

Note that list blocks do not render anything in your store. Instead, they hold content that can be edited using Site Editor and pass it down to their child blocks.

Now that you have specified which information, an image in this case, will be displayed in your slider using a list block, you need to configure the slider properties themselves, meaning the properties of slider-layout.

Example:


_26  "list-context.image-list#demo": {
_26    "children": ["slider-layout#demo-images"],
_26    "props": {
_26      "height": 650,
_26      "images": [
_26        {
_26          "image": "https://storecomponents.vteximg.com.br/files/banner-infocard2.png",
_26          "description": "something something"
_26        },
_26        {
_26          "image": "https://storecomponents.vteximg.com.br/assets/vtex.file-manager-graphql/images/Group%207%20(1)%20(1)%20(1)%20(1)%20(1)___c6b3ed853fb16a08b265753b50e0c57a.png",
_26          "description": "something something"
_26        }
_26      ]
_26    }
_26  },
_26  "slider-layout#demo-images": {
_26    "props": {
_26      "itemsPerPage": {
_26        "desktop": 1,
_26        "tablet": 1,
_26        "phone": 1
_26      },
_26      "infinite": true
_26    }
_26  }

Now you have a fully functioning carousel for your store.

{"base64":" ","img":{"width":2860,"height":1396,"type":"gif","mime":"image/gif","wUnits":"px","hUnits":"px","length":1262350,"url":"https://cdn.jsdelivr.net/gh/vtexdocs/dev-portal-content@main/images/vtex-io-documentation-building-a-carousel-using-slider-layout-0.gif"}}

When inspecting the page, you will notice that the carousel block was not used to build the component.

Note that you can also edit the information contained in list-context.image-list through Site Editor section in the Admin:

{"base64":" ","img":{"width":2874,"height":1638,"type":"png","mime":"image/png","wUnits":"px","hUnits":"px","length":925830,"url":"https://cdn.jsdelivr.net/gh/vtexdocs/dev-portal-content@main/images/vtex-io-documentation-building-a-carousel-using-slider-layout-1.png"}}
