Creating shared content list in Sitecore JSS

If you are working with Sitecore JSS, you may require to share some common data with multiple components.  

If you are new to Sitecore JSS world, this article is for you. Here I am taking example of Tags component to show tags in blog website.
For this you must create a template in Sitecore JSS application at “sitecore\definitions\templates\KeyValue-Template.sitecore.js” as

// eslint-disable-next-line no-unused-vars
import { CommonFieldTypes, Manifest } from '@sitecore-jss/sitecore-jss-manifest';

 * This is the data template for an individual _item_ in the Tag's Content List field demo.
 * @param {Manifest} manifest Manifest instance to add components to
export default function(manifest) {
    name: 'KeyValue-Item-Template',
    fields: [{ name: 'KeyValue', type: CommonFieldTypes.SingleLineText }],

You can add one or more fields in template function here.

On Sitecore JSS application deployment, this file will create a template “KeyValue-Item-Template” in Sitecore with single field “KeyValue” as

Tags Template
Tags Template

Create some content items based on this template in Sitecore JSS application at “data\content\Tags\ContentListField\Item2\en.yml” as

id: Tag-2
displayName: Tag
# Template defines the available fields. See /sitecore/definitions/templates/KeyValue-Template.sitecore.js
template: KeyValue-Item-Template
  KeyValue: Long Tag

I have created 4 such tags files in Sitecore JSS application.

On Sitecore JSS application deployment, these files will create items in Sitecore content tree at “/sitecore/content/my-first-jss-app/Content/Tags/ContentListField/Item2” as

Tags Items
Tags Items

Till this we have created shared items. Now its time to consume these items in Sitecore treelist.

For this, add new component in Sitecore JSS application using “jss scaffold” command.

I have added “BlogTagComponent” and its definition file is located at “sitecore\definitions\components\BlogTagComponent.sitecore.js” in JSS application.

// eslint-disable-next-line no-unused-vars
import { CommonFieldTypes, SitecoreIcon, Manifest } from '@sitecore-jss/sitecore-jss-manifest';
import packageJson from '../../../package.json';
 * Adds the BlogTagComponent component to the disconnected manifest.
 * This function is invoked by convention (*.sitecore.js) when 'jss manifest' is run.
 * @param {Manifest} manifest Manifest instance to add components to
export default function(manifest) {
    name: 'BlogTagComponent',
    icon: SitecoreIcon.DocumentTag,
    fields: [
      { name: 'heading', type: CommonFieldTypes.SingleLineText },
      { name: 'tagContentList', type: CommonFieldTypes.ContentList,
      source: `dataSource=/sitecore/content/${
      }/Content/Tags/ContentListField`, },     
    If the component implementation uses <Placeholder> or withPlaceholder to expose a placeholder,
    register it here, or components added to that placeholder will not be returned by Sitecore:
    placeholders: ['exposed-placeholder-name']
    // placeholders: ['jss-BlogTagComponent'],

I have added two fields in BlogTagComponent – heading and tagContentList.

Field “tagContentList” is specified in JSS application as “ContentList” field type which is Treelist in Sitecore and I set its data source at our Tags collection item.

After Sitecore JSS application deployment, this BlogTagComponent file will create template item in Sitecore as

BlogTagComponent Template
BlogTagComponent Template

This scaffold command create one more file “src\components\BlogTagComponent\index.js” where we can specify our HTML code as

import React from 'react';
import { Text } from '@sitecore-jss/sitecore-jss-react';

const BlogTagComponent = (props) => {
  const { heading, tagContentList } = props.fields;

  return (

    <div class="container tags-topics">
        <button class="btn btn-info">
            <Text field={heading} />

        <div class="card bg-dark">
            {tagContentList &&, index) => (
                  <a class="btn btn-info" id={`tagBlogListItem-${index}`} href="#" role="button">
                      <Text field={listItem.fields.KeyValue} />

export default BlogTagComponent;

To access all selected tags here, we have to iterate it using “, index) => ()” code. Inside this map() function, we can access selected items one by one.

On Sitecore JSS application deployment, this BlogTagComponent file will create rendering item in Sitecore as

BlogTagComponent Rendering item
BlogTagComponent Rendering item
Finally, you should specify this BlogTagComponent in any route file where route file is your page item in Sitecore.

  - componentName: BlogTagComponent
      heading: Tags, Topics & Archive     
      # see /data/content/Tags/ContentListField for definitions of these IDs
      - id: Tag-1
      - id: Tag-4

On deployment, this component will show in Sitecore under page item as

Tags in BlogTagComponent
Tags in BlogTagComponent

As you can notice here we have selected two tags out of 4 available tags and that’s it.

Learning from this example - For any common and reused type of content, always create shared list in Sitecore JSS based applications.

I hope you enjoyed this Sitecore JSS article.

Happy JSS 😉.
