A Vanilla.js Package to Convert a Nested List Into a Tree Menu

A Vanilla.js Package to Convert a Nested List Into a Tree Menu

listree is an extremely lightweight JavaScript library to create a minimal, clean, collapsible tree structure from nested HTML lists.

A tiny package to easily create a tree menu.

Example Usage

Include listree.min.css and listree.min.umd.js in the header and footer respectively. Make sure that the unordered list in the html has class-markers like below (Should be easy to generate via any server side templating language. ). Then just invoke listree(). It will scan the document for the class markers and convert the ul list into a tree

<!DOCTYPE html>

    <link rel="stylesheet" href="https://unpkg.com/listree/dist/listree.min.css"/>
    <title>LisTree</title>
