    copied!<p>Yes, this is definitely possible, but you have to use <a href="https://developers.facebook.com/docs/guides/web/" rel="nofollow noreferrer">Facebook Connect</a> and <a href="http://wiki.developers.facebook.com/index.php/XFBML" rel="nofollow noreferrer">XFBML</a>. Specifically, you want to use the <a href="https://developers.facebook.com/docs/reference/fbml/serverFbml/" rel="nofollow noreferrer">fb:serverfbml</a> tag to get fb:friend-selector working. I have an iframe app whereby I use all of this and the fb:friend-selector in the standard "invite friends to your app" context, and it works great.</p> <p>Here is the body of my template file, which gets output inside the body of my iframe:</p> <pre class="lang-html prettyprint-override"><code>&lt;fb:serverfbml style="width: 650px;"&gt; &lt;script type="text/fbml"&gt; &lt;fb:fbml&gt; &lt;fb:request-form action="http://example.com/invite/sent" method="POST" invite="true" type="My App" content="Try out my app! &lt;fb:req-choice url='http://your-facebook-canvas-url' label='&lt;?php echo htmlspecialchars("Accept button text",ENT_QUOTES); ?&gt;' /&gt; " &gt; &lt;fb:multi-friend-selector showborder="false" actiontext="Invite your friends to try My App." exclude_ids="&lt;?php echo $excludeIds; ?&gt;" rows="3" /&gt; &lt;/fb:request-form&gt; &lt;/fb:fbml&gt; &lt;/script&gt; &lt;/fb:serverfbml&gt; </code></pre> <p>In the footer of the page, I have the standard Facebook Connect code, which will load and render the fb:serverfbml contents:</p> <pre class="lang-html prettyprint-override"><code>&lt;script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; FB_RequireFeatures( ["CanvasUtil"], function(){ FB.XdComm.Server.init('/xd_receiver.html'); FB.CanvasClient.startTimerToSizeToContent(); } ); &lt;/script&gt; &lt;script type="text/javascript"&gt; FB_RequireFeatures(["XFBML"], function(){ FB.Facebook.init("Your Facebook API Key", "/xd_receiver.html"); }); &lt;/script&gt; </code></pre> <p>That should be all you need (fill in your own options where applicable, of course). You'll have to set up Facebook Connect to work with a cross-domain receiver file. I suggest following the <a href="http://wiki.developers.facebook.com/index.php/XFBML#Rendering_XFBML" rel="nofollow noreferrer">rendering XFBML steps</a>.</p>
