    <p>I got interested in this, so I've written the starting point for a full solution. The following uses my <a href="http://code.google.com/p/rangy/" rel="nofollow">Rangy library</a> with its <a href="http://code.google.com/p/rangy/wiki/SelectionSaveRestoreModule" rel="nofollow">selection save/restore module</a> to save and restore the selection and normalize cross browser issues. It surrounds all matching text (@whatever in this case) with a link element and positions the selection where it had been previously. This is triggered after there has been no keyboard activity for one second. It should be quite reusable.</p> <pre><code>function createLink(matchedTextNode) { var el = document.createElement("a"); el.style.backgroundColor = "yellow"; el.style.padding = "2px"; el.contentEditable = false; var matchedName = matchedTextNode.data.slice(1); // Remove the leading @ el.href = "http://www.example.com/?name=" + matchedName; matchedTextNode.data = matchedName; el.appendChild(matchedTextNode); return el; } function shouldLinkifyContents(el) { return el.tagName != "A"; } function surroundInElement(el, regex, surrounderCreateFunc, shouldSurroundFunc) { var child = el.lastChild; while (child) { if (child.nodeType == 1 &amp;&amp; shouldSurroundFunc(el)) { surroundInElement(child, regex, surrounderCreateFunc, shouldSurroundFunc); } else if (child.nodeType == 3) { surroundMatchingText(child, regex, surrounderCreateFunc); } child = child.previousSibling; } } function surroundMatchingText(textNode, regex, surrounderCreateFunc) { var parent = textNode.parentNode; var result, surroundingNode, matchedTextNode, matchLength, matchedText; while ( textNode &amp;&amp; (result = regex.exec(textNode.data)) ) { matchedTextNode = textNode.splitText(result.index); matchedText = result[0]; matchLength = matchedText.length; textNode = (matchedTextNode.length &gt; matchLength) ? matchedTextNode.splitText(matchLength) : null; surroundingNode = surrounderCreateFunc(matchedTextNode.cloneNode(true)); parent.insertBefore(surroundingNode, matchedTextNode); parent.removeChild(matchedTextNode); } } function updateLinks() { var el = document.getElementById("editable"); var savedSelection = rangy.saveSelection(); surroundInElement(el, /@\w+/, createLink, shouldLinkifyContents); rangy.restoreSelection(savedSelection); } var keyTimer = null, keyDelay = 1000; function keyUpLinkifyHandler() { if (keyTimer) { window.clearTimeout(keyTimer); } keyTimer = window.setTimeout(function() { updateLinks(); keyTimer = null; }, keyDelay); } </code></pre> <p>HTML:</p> <pre><code>&lt;p contenteditable="true" id="editable" onkeyup="keyUpLinkifyHandler()"&gt; Some editable content for @someone or other &lt;/p&gt; </code></pre>

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.

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