<p>
Use the <b>contextMenuOf</b> property of the <b>Menu</b> component
to specify elements where the menu should be used as a
context menu.
</p>
<p>
Every element in the array can be referenced using its <i>id</i> or
a React <i>ref</i>.
</p>
<div className="owners">
<div id="first" style={{ background: '#f0a0a0' }} tabIndex={0}>
I have a Context Menu (bound by id attribute).
</div>
<div id="second" style={{ background: '#a0f0a0' }} ref={divRef} tabIndex={0}>
I have the same Context Menu (bound by React ref).
</div>
</div>
<h4>The same approach works with all Wijmo controls:</h4>
