Generates a series of nested accordions (using the details/summary elements) from a json datafile
$ yarn add nested-accordion
const nestedAccordion = require('nested-accordion');const nestedAccordionDiv = nestedAccordion.create(data)Title is required, optional text and children. If both text and children are ommitted, that child accordion will be diabled
type SectionData = {
title: string;
text?: string;
children?: Array<SectionData>;
};Optional colour parameters default to grey boxes
const styles = nestedAccordion.styles(
activeColour: 'grey',
inactiveColor: 'lightgrey',
textColor: 'black')
export css = `<style>\n${styles}\n</style>` const data = [

const css = `<style>${nestedAccordion.styles('cyan', 'lightcyan')}</style>`
const div = nestedAccordion.create(data)Then when the css string is put in the body of the page, and the div where you want the accordion to appear, to looks like:

This can be used to visualise large mind-map style datasets, for example on this site looking tinto university courses.
If you want to use this accordion for you project, but it isn't quite working, let me know and I'll see what I can do!
