How to append div tag into a SVG rect element?

Question

I couldn\'t find a correct solution for this problem so I decided to write a new question.

I\'m not even sure that this is possible but I hope it is.

So here is

Unfortunately, it's not possible: you cannot append an HTML element to an SVG element.

The only way for using a div (or a p, h1, li etc) in an SVG is by using foreignObject. In your code, something like this:

<svg width="960" height="728" style="margin-left: 0px;">
<g transform="translate(0,24)" style="shape-rendering: crispEdges;">
    <g class="depth">
        <g>
            <g>
                <rect class="child" x="0" y="0" width="960" height="704" style="fill: rgb(192, 192, 192);">
                </rect>
                <foreignObject x="100" y="100" width="100" height="100">
		    <div xmlns="http://www.w3.org/1999/xhtml" class="jstree">
                        <div>TestContent</div>
                    </div>
	        </foreignObject>
            </g>
        </g>
    </g>
</g>

Notice that foreignObject comes after the rectangle, not inside it (as in your code). Also, notice that foreignObject does not work in IE: https://developer.mozilla.org/en/docs/Web/SVG/Element/foreignObject
