    <p>If <code>intersection</code> is a list of IDs, it's really simple.</p> <p>Using straight DOM methods (no jQuery), you can use <a href="http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html#ID-getElBId" rel="nofollow"><code>getElementById</code></a> to look up each element, <a href="http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html#ID-1060184317" rel="nofollow"><code>parentNode</code></a> to get its parent node, and then <a href="http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html#ID-1734834066" rel="nofollow"><code>removeChild</code></a> to remove it:</p> <pre><code>var index; for (index = 0; index &lt; intersection.length; ++index) { elm = document.getElementById(intersection[index]); elm.parentNode.removeChild(elm); } </code></pre> <p>But it's worth noting that jQuery works around <a href="http://blog.niftysnippets.org/2010/03/by-any-other-name-would-smell-as-sweet.html" rel="nofollow">bugs in IE6's and IE7's implementation</a> of <code>getElementById</code>, so if you're already using jQuery, you may want to use it for this as well to get the advantage of those workarounds.</p> <p>Or use jQuery's <a href="http://api.jquery.com/remove/" rel="nofollow"><code>remove</code></a>:</p> <pre><code>var index; for (index = 0; index &lt; intersection.length; ++index) { $("#" + intersection[index]).remove(); } </code></pre> <p>Or if you like, use jQuery's <a href="http://api.jquery.com/jQuery.each/" rel="nofollow"><code>each</code></a> with <code>remove</code>:</p> <pre><code>$.each(intersection, function(index, value) { $("#" + value).remove(); }); </code></pre> <p><strong>Update 2011/04/29</strong>: Or you can take advantage of <code>Array#join</code> to create a selector in the form <code>#id1, #id2, #id3</code> and them remove them with one call:</p> <pre><code>$('#' + intersection.join(', #')).remove(); </code></pre> <hr> <p><strong>Update</strong>: There's some discussion of making sure that the elements are <code>li</code> elements. If you really need to do that, here are the three above, modified:</p> <p>Straight DOM (added the <code>if</code>):</p> <pre><code>var index; for (index = 0; index &lt; intersection.length; ++index) { elm = document.getElementById(intersection[index]); if (elm.tagName === "LI") { elm.parentNode.removeChild(elm); } } </code></pre> <p>jQuery options (literally just add "li" in front of "#" to say "the element with this ID, but only if it's a <code>li</code>"):</p> <p>For loop:</p> <pre><code>var index; for (index = 0; index &lt; intersection.length; ++index) { $("li#" + intersection[index]).remove(); } </code></pre> <p>Using <code>each</code>:</p> <pre><code>$.each(intersection, function(index, value) { $("li#" + value).remove(); }); </code></pre> <p><strong>Update 2011/04/29</strong>: Using <code>Array#join</code>:</p> <pre><code>$('li#' + intersection.join(', li#')).remove(); </code></pre>

    2. CO@Patrioticcow: When you're using `id` values, it doesn't matter what kind of element (`li`, etc.) it is or where it is. `id` values must be unique, so if you find it at all, you'll find it anywhere. But if you're writing something that should only process these elements if they have the `id` value *and* are `li` elements or are in some particular place, you can do that with various jQuery selectors. jQuery supports nearly all of CSS3 and has quite a few enhancements as well. Your specific example would be matched by "'div[is=test] > li#' + id", so: `$('div[is=test] > li#' + id).remove();`

    3. CO@Patrioticcow: More about jQuery selectors [here](http://api.jquery.com/category/selectors/). Off-topic: Your "is" attribute is invalid ("is" is not a valid attribute for `div` elements). If you want to have custom attributes, prefix them with "data-" (so, for instance, `<div data-is="test">`). All attributes prefixed with "data-" are ignored by validators as of HTML5.

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.
