Configuration

Then create a file called addons.js in your storybook config and add following content to it:

import "storybook-addon-root-attribute/register";

or create a file called main.js and add addon in addons section:

module.exports = {
  ...
  addons: [
    ...
    'storybook-addon-root-attribute/register'
  ]
};

Usage

You need add the all the attribute values at compile time using the withRootAttribute decorator. They can be added globally or per story. You can then choose which ones root attribute activate on addon ui:

// Import from @storybook/X where X is your framework
import {
  configure,
  addDecorator,
  addParameters,
  storiesOf
} from "@storybook/react";
import { withRootAttribute } from "storybook-addon-root-attribute";

// global
addDecorator(withRootAttribute);
addParameters({
  rootAttribute: {
    defaultState: {
      name: "Default",
      value: null
    },
    states: [
      {
        name: "Dark",
        value: "dark"
      }
    ]
  }
});

You can use the rootAttribute parameter to override resources on each story individually:

// per story
storiesOf("Addons|RootAttribute", module).add(
  "Camera Icon",
  () => <i className="fa fa-camera-retro"> Camera Icon</i>,
  {
    rootAttribute: {
      defaultState: {
        name: "Default",
        value: null
      },
      states: [
        {
          name: "Dark",
          value: "dark"
        }
      ]
    }
  }
);

If you want to use a tooltip (panel will not dissapear), you need to set tooltip in parameters with true value:

addParameters({
  rootAttribute: {
    tooltip: true,
    defaultState: {
      name: "Default",
      value: null
    },
    states: [
      {
        name: "Dark",
        value: "dark"
      }
    ]
  }
});

Tooltip and panel will not sync about change attribute.
