This sample demostrates the use of the ZoomSlider extension. When using the ZoomSlider extension, the diagram Div must always be a direct child of a Div
using <code>position: relative</code> or <code>position: absolute</code>, so that the ZoomSlider HTML DOM can be positioned correctly relative to the
Diagram Div.
</p>
<p>This extension HTML is defined in its own file, as <a href="../extensions/ZoomSlider.js">ZoomSlider.js</a> and <a href="ZoomSlider.css">ZoomSlider.css</a>.</p>

<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>GoJS Extensions</h4>
<p>
<b>GoJS</b> can be extended in a variety of ways.
The most common way to change the standard behavior is to set properties on the <a href="../api/symbols/GraphObject.html" target="api">GraphObject</a>, <a href="../api/symbols/Diagram.html" target="api">Diagram</a>, <a href="../api/symbols/CommandHandler.html" target="api">CommandHandler</a>, <a href="../api/symbols/Tool.html" target="api">Tool</a>, or <a href="../api/symbols/Layout.html" target="api">Layout</a>.
But when the desired property does not exist, you might need to override methods of CommandHandler, Tool, Layout, Link, or Node.
Methods that you can override are documented in the API reference.
Various features of GoJS can be overriden, either by replacing a method on an instance (a feature of JavaScript) or by defining a subclass.
You should not modify the prototypes of any of the <b>GoJS</b> classes.
</p>
<p>
In addition to our samples, <b>GoJS</b> provides an <strong><a href="../samples/#extensions">extensions gallery</a></strong>,
showcasing the creation of custom tools and layouts.
Those classes and samples are written in TypeScript, available at <code>../extensionsJSM/</code>,
as ECMAScript/JavaScript modules -- these use the <code>../release/go-module.js</code> library.
We recommend that you copy the files that you need into your project, so that you can adjust how they refer to the GoJS library
that you choose and so that you can include them into your own building and packaging procedures.

<h4>HTML Interaction</h4>
<p>
GoJS Diagrams can be used alongside other HTML elements in a webapp.
For custom Text Editors, Context Menus, and ToolTips, which are invoked and hidden via GoJS tool operations, it is best to use the <a href="../api/symbols/HTMLInfo.html" target="api">HTMLInfo</a> class.
