Composable Content

Composable content is a react-based tool to visually build up content as JSON, as a replacement for a traditional WYSIWYG editor.

The idea is to take re-usable components and let the author drag and drop those components, reorder and edit as they need.

Composable content was originally developed for Koi but has since been split out in to a standalone react component.

Bare with us this component still needs plenty of documentation and testing.

  3. Props


You can view the online storybook to see some use-cases and examples.

You can run the storybook locally by cloning this repo and running yarn storybook


First add the npm package:

yarn add react-composable-content

Then consume the component in your project:

import Composable from 'react-composable-content';
import * as icons from 'react-composable-content/icons';
import 'react-composable-content/react-composable-content.css';
        main: ["text"]
          name: "text",
          label: "Text",
          fields: [{
            name: "text_field",
            label: "Text",
            type: "text",



An object containing named groups and an array of component names for those groups:

  main: ["component1", "component2, component7"],
  sidebar: ["component3", "component15"]

This will configure two groups, "main" and "sidebar".
Main will be allowed to drag in component1, component2 and component7.
Sidebar will only be allowed to drag in component3 and component15.


    name: "my_component",
    label: "This is my custom component",
    icon: "paragraph",
    fields: [{
      name: "first_name",
      label: "First name",
      type: "string",
      name: "address",
      label: "Address",
      type: "text",

Components can have the following properties:

prop optional description
name An internal slug-like name for the component, used to ID the component in your config
label The user-visible label for the component
primary optional The primary field used in the preview area of the component
message optional A message to appear at the top of the component
messageType optional A class to appear on your message
icon optional The icon used for your component, will appear in the list of components on the right and in the header of the component
fields optional An array of fields for this component. If there are no fields defined the user will see "This component doesn't require configuration"

Fields can have the following properties:

prop optional description
name An internal slug-like name for the field
label The label of the field as it appears to the user
type optional The name of the react component to render for the field, eg "string" => "ComposableFieldString", "other_field" => "ComposableFieldOtherfield" etc.
hint optional A hint message to appear between the label and the field
defaultValue optional The default value for the input field
wrapperClass optional Custom class for the element that wraps around the label/hint/field/error etc.
className optional Custom class for the input field itself
data conditionally Required for select, checkbox or radios. Can be either an array of values - [1,2,3] or an array of objects - [{ name: "one", value: 1 },{ name: "two", value: 2 }]
fieldAttributes optional Any custom html attributes you need for the input field, can be used for requiredness
fields conditional Nested fields, applicable only to the repeater field type


An array of inline SVG code for icons.
It's recommended you use the react-composable-content/icons import to configure your icons.

  cog, visible, myCustomIcon, myOtherCustomIcon,

These icons can be used in your component configuration


Composable content can be used inside a form element to render a hidden input field to save the JSON result to your database.
This prop is the name attribute of the hidden input field.


Boolean to enable components to be marked as drafts.


A series of form fields to show in the advanced menu of components.
If this prop is not present the advanced settings menu will be removed altogether.

  name: "css_class",
  label: "Class (CSS)",
  type: "string",

You can have as many advanced fields as you like.


Set to true to show the JSON output under your composable content


You can translate / override various strings in the component with your own strings:

  • emptyComposition
  • collapseAll
  • revealAll
  • remove
  • draftModeBanner

Callback functions / integration options

If you're implementing composable content inside a larger system you can take advantage of some of the more advanced integration props and callbacks to manage data flow or trigger other events.


Callback function to run when the component mounts


Callback function to run when the composition is changed

onCompositionChange={(json) => {


Callback function to run when dragging starts
This piggybacks off of react-beautiful-dnd so the arguments are the same:

onDragStart={(start, provided) => {


Callback function to run when dragging stops and the composition has been updated
This piggybacks off of react-beautiful-dnd so the arguments are the same:

onDragStart={(result, provided) => {





npm i react-composable-content
