    <p>There's not a quick or easy answer to this but with a bit of creative cajoling we can emulate the same functionality.</p> <p>What we need is a series of elements we can identify, loop over and then set up so that when we hit their position on the page the previous item is pushed up and the new item becomes fixed. We will need to retrieve the element's initial position using jQuery's <code>offset().top</code> method and store it in a <code>data</code> tag so we can reference it later. Then the rest will be calculated as we scroll.</p> <p><strong>This should do the trick:</strong></p> <p><div class="snippet" data-lang="js" data-hide="false" data-console="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>var stickyHeaders = (function() { var $window = $(window), $stickies;

    1. COChris, I was able to get that to work before. However when I scroll back up it skips the other headers and jumps to the top, instead of replacing it with the previous one.

    2. COSorry I was pressed for time and didn't notice it not "docking". I've modified the script. The problem was I needed to store the original position to evaluate against. So I've used jQuery.data to store the element's original top position in the ready event. then when the page is scrolled it evaluates the windows offset against that of the pos we stored on the element. if its less than or equal we add a class of fixed otherwise we remove it.

    3. COThanks for staying up with this. While your headers do switch off, they do not "push up" like in the Instagram iPhone app which is what I'm really looking for.

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).
