    <p>Since you have control over the content in the iframe you could try window <a href="https://developer.mozilla.org/en-US/docs/DOM/window.postMessage" rel="nofollow" title="message">message</a> events.</p> <p>Add this to your frame content:</p> <pre><code>// post a message to the top window with information about the height window.onload = function(){ top.postMessage(document.body.scrollHeight, '*'); } </code></pre> <p>And this to your page containing the iframe:</p> <pre><code>// listen for the message and set the iframe height when it arrives window.addEventListener( "message", function(event){ document.getElementById('test').style.height = event.data+'px'; }, false); &lt;iframe id="test" src="test.html"/&gt; </code></pre> <hr> <p>In response to your comment. Here are some ways you can update the iframe height when the iframe content changes.</p> <p><strong>1.</strong> <a href="https://developer.mozilla.org/en-US/docs/DOM/Mutation_events" rel="nofollow" title="Mutation Events">Mutation Events</a></p> <pre><code>// listen to all descendants of the body and if there are any modifications, post an update to the top window document.body.addEventListener("DOMSubtreeModified", function(){ top.postMessage(document.body.scrollHeight, '*'); }, false); </code></pre> <p>That approach has been depreciated. This is the replacement but it is not yet fully supported:</p> <p><strong>2.</strong> <a href="https://developer.mozilla.org/en-US/docs/DOM/MutationObserver?redirectlocale=en-US&amp;redirectslug=DOM/DOM_Mutation_Observers" rel="nofollow" title="Mutation Observers">Mutation Observers</a></p> <pre><code>// create a MutationObserver to listen for modification to the body and post an update to the top window var observer = new MutationObserver(function(){ top.postMessage(document.body.scrollHeight, '*'); }); observer.observe(document.body, {childList: true, subtree: true}); </code></pre> <p>I would go with the first option until the second is better supported</p>

    1. COThis works to set the iframe initially, but there is one issue. Let's say the user loads up the page, sees all the posts and clicks on one. What happens is if the post is longer than the original iframe height, the iframe will not automatically resize to accomodate for the new length. I don't know enough to fix this...

    3. COThis time, instead of expanding the actual height of the iframe, it adds a scroll bar and keeps the iframe height static to what it was set upon first load of the page. Of course, I might be putting this new code in the wrong place. I tried both the iframe content page and the page containing the iframe

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
