Accordion

Accordions can make content-heavy pages appear less so by vertically stacking items in lists that users can expand or contract.

Read more about when and how to use the Accordion component on the internal wiki.

Getting started

Install the package

yarn add @hig/accordion @hig/theme-context @hig/theme-data

Import the component

import Accordion from "@hig/accordion";

Basic usage

<Accordion label="foo">
  bar
</Accordion>

Customization

Indicator

The icon and position of the indicator can be customized by props, available values can be found via:

import {
  indicators,
  indicatorPositions,
  AVAILABLE_INDICATORS,
  AVAILABLE_INDICATOR_POSITIONS
} from "@hig/accordion";

Styling

Use the className prop to pass in a css class name to the outermost container of the component. The class name will also pass down to most of the other styled elements within the component.

Accordion also has a stylesheet prop that accepts a function wherein you can modify Accordion's styles. The original styles, props, current theme data and theme meta will be passed to your custom stylesheet function, and it should return an object with the same structure as the original styles. For instance

function customStylesheet(styles, props, themeData, themeMeta) {
  return {
    ...styles,
    wrapper: {
      ...styles.wrapper,
      backgroundColor: "yellow"
    },
    header: {
      ...styles.header,
      backgroundColor: props.collapsed
        ? themeData["basics.colors.green100"]
        : themeData["basics.colors.darkBlue100"]
    }
  };
}

<Accordion stylesheet={customStylesheet} label="foo">
  bar
</Accordion>
