    <p>By "editable content window" I'm going to assume you mean an element with <code>contenteditable</code> turned on or a document with <code>designMode</code> turned on.</p> <p>There are also two cases to consider: the case when the user has made a selection and the case where there is just a caret. The code below will work in both cases, and will give you the innermost <strong>element</strong> that completely contains the selection. If the selection is completely contained within a text node it's slightly complicated to get that text node in IE (trivial in other browsers), so I haven't provided that code here. If you need it, I can dig it out.</p> <pre><code>function getSelectionContainerElement() { var range, sel, container; if (document.selection &amp;&amp; document.selection.createRange) { // IE case range = document.selection.createRange(); return range.parentElement(); } else if (window.getSelection) { sel = window.getSelection(); if (sel.getRangeAt) { if (sel.rangeCount &gt; 0) { range = sel.getRangeAt(0); } } else { // Old WebKit selection object has no getRangeAt, so // create a range from other selection properties range = document.createRange(); range.setStart(sel.anchorNode, sel.anchorOffset); range.setEnd(sel.focusNode, sel.focusOffset); // Handle the case when the selection was selected backwards (from the end to the start in the document) if (range.collapsed !== sel.isCollapsed) { range.setStart(sel.focusNode, sel.focusOffset); range.setEnd(sel.anchorNode, sel.anchorOffset); } } if (range) { container = range.commonAncestorContainer; // Check if the container is a text node and return its parent if so return container.nodeType === 3 ? container.parentNode : container; } } } </code></pre>

    1. COTim, this is exactly what I was looking for. I would appreciate if you can also dig in the IE case where selection is contained with in a text node. Thanks.

    2. COBtw, the IE case where you return range.parentElement() always seems to return the body element even though the caret was in text that inside an anchor node eg. In this HTML <a href="http://www.stackoverflow.com">xyz</a> if the caret was in between say 'x' and 'y', shouldn't parentElement() return the 'a' node?

    3. COYes, it should. I haven't had problems with `parentElement()` before - have you got a page I can look at showing the problem?

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).
