    <p>I need to add <code>rel="lightbox"</code> to the anchor tag when you select a target image using either Image or TextImage component. The anchor tag is automatically generated by CQ, but I am unable to find where this happens, or more importantly, if there is a method I can call to add this string.</p> <p>I am looking over the Adobe documentation for the built-in Image component (<a href="http://dev.day.com/docs/en/cq/5-3/javadoc/com/day/cq/wcm/foundation/Image.html" rel="nofollow">http://dev.day.com/docs/en/cq/5-3/javadoc/com/day/cq/wcm/foundation/Image.html</a>), which I cloned and modified slightly for separate Lightbox use.</p> <p>Image object has <code>protected Map&lt;String,String&gt; getImageTagAttributes()</code>, and I hope there is some equivalent object for anchors in a class that I'm not aware of.</p> <p>Here is our current Image component that I used for reference.</p> <pre><code>&lt;%@ page import="commons.Doctype, wcm.api.components.DropTarget, wcm.foundation.Image" %&gt;&lt;% %&gt;&lt;%@include file="/apps/site/global.jsp"%&gt;&lt;% String alignment = properties.get("alignment", ""); Image image = new Image(resource); //drop target css class = dd prefix + name of the drop target in the edit config image.addCssClass(DropTarget.CSS_CLASS_PREFIX + "image"); if (!alignment.isEmpty() &amp;&amp; !alignment.equals("center")) image.addCssClass(alignment); image.loadStyleData(currentStyle); image.setSelector(".img"); // use image script image.setDoctype(Doctype.fromRequest(request)); // add design information if not default (i.e. for reference paras) if (!currentDesign.equals(resourceDesign)) { image.setSuffix(currentDesign.getId()); } if (alignment.equals("center")) { %&gt;&lt;div class="center"&gt;&lt;% } %&gt;&lt;% image.draw(out); %&gt;&lt;% %&gt;&lt;cq:text property="jcr:description" placeholder="" tagName="small"/&gt; &lt;% if (alignment.equals("center")) {%&gt; &lt;/div&gt; &lt;% } %&gt; </code></pre> <p>Right now I'm using jQuery to do the job, but I don't want to rely on scripting if possible.</p>

    1. COThis is perhaps a cheesy way to do it, but we solved this problem by avoiding the `<% image.draw(out)%>` call; instead we just emit something like `<img src="<%=image.getSrc()%>"...><a rel="lightbox"...`.

    2. COWhat about if a target image isn't selected? Do you have a conditional for that? The hyperlink has to wrap round the source image only if a target image is found.

    3. COHmm, not sure about that. Perhaps the getHref() and getInnerHtml() methods of [DownloadResource](http://dev.day.com/docs/en/cq/5-3/javadoc/com/day/cq/commons/DownloadResource.html), from which Image inherits, could be useful?

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.
