Why the whole?
Maybe ask yourself. There are many good and extensive sites on the net, for all the topics presented here. So why a new page with old content?
Well, I see, at least for my person, need for additional examples. I was forced to convert a Java application to a Web application. So my journey began through the Web to provide me with information about the HowTo, which ultimately led to success after many days and considerable frustration. Many of the examples found were difficult to understand for beginners, as these obviously required a certain amount of basic knowledge. There are e.g. a page where code examples can be followed live. The examples available there work more or less well. However, I could not understand in any case why examples work there, but not with me (very frustrating !!). This is based, according to my findings, that although the code is published there, but not the requirements (required libraries, etc.) My basic knowledge was partly sparse (java script) to me (jquery, tree representation on a web page). Therefore, I have decided to make my experiences gained here public, to facilitate others the stony path to success. I would be happy if I succeeded.

<"JavaScript often abbreviated as JS, is a high-level, interpreted programming language. It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.
Alongside HTML and CSS, JavaScript is one of the three core technologies of the World Wide Web. JavaScript enables interactive web pages and thus is an essential part of web applications. The vast majority of websites use it, and all major web browsers have a dedicated JavaScript engine to execute it.>"

The examples shown on these pages use JavaScript.
To understand this, it is necessary that you are familiar with java script.
Here is an tutorial in english: JavaScript Tutorial
And here is a german tutorial: selfhtml JavaScript

The examples shown on these pages also use libraries from JQuery.

Here is an (English) tutorial: JQuery Tutorial
Therefore, it is necessary that you download the JQuery javaScript libraries.

Last but not least, the CSS script library jquery-ui.css, or jquery-ui.min.css are needed.
So, now you are almost ready for the first example:
The first thing you need to do is download the vkata / jstree library from the jstree homepage or from GitHub vakata / jstree.

<"JavaServer Pages (JSP) is a technology that helps software developers create dynamically generated web pages based on HTML,
XML, or other document types. Released in 1999 by Sun Microsystems, JSP is similar to PHP and ASP, but it uses the Java programming language.
To deploy and run JavaServer Pages, a compatible web server with a servlet container, such as Apache Tomcat or Jetty, is required.">
In the chapter "vakata / jstree", the topic of creating a tree is treated with javaScript and the librariesybr/> vakata / jstree and jQuery, and also jquery-ui.min.css
Here is the tree structure from the chapter "vakata / jstree" in JavaServerPages (jsp).

<"PHP (PHP: Hypertext Preprocessor) is a scripting language that helps people make web pages more interactive by allowing them
to do more things. PHP code is run on the web server. A website programmed with PHP can have pages that are password protected.
A website with no programming cannot do this without other complex things. Standard PHP file extensions are: .php .php3 or .phtml,
but a web server can be set up to use any extension. Its structure was influenced by many languages like C, Perl, Java, C++, and even Python.
It is considered to be free software by the Free Software Foundation. Wikipedia, which runs on MediaWiki, uses the PHP scripting language.">
