Pure CSS Window Style Collapsible Tree Menu With Folder/File Icons

A tree menu is a useful element to present hierarchical data in the visual interface of a website. It is most commonly used in file management systems to allow users to explore the folder and files. Basically, a simple tree-view navigation can be created using HTML nested lists. But in order to make each list collapsible, we need a JavaScript function to toggle the height of the list. Luckily, we can also make them collapsible using the HTML checkbox element and CSS. Well, in this tutorial, we are going to create a collapsible tree menu using pure CSS.

Here we have a pure vanilla JavaScript snippet that helps you create a simple image slider with basic carousel functionalities such as infinite scrolling, autoplay, responsive and navigation with bullet points.

There are many code snippets available online or on many other blogs and websites, but everyone cannot optimize your blog or website, so you need some optimized code snippets. So now checkout out the code snippet for your blog and website that will give you all features for your desired code. Now grab the ready-to-use code and paste it where you want.

Features:

1. Light Weight.
2. Pure JavaScript Code.
3. Cross Browser.
4. No External Files.
5. Fully Customizable.
