    <p>Could someone help me with this code? I'm trying to rearrange figures in a certain div into two columns (a and b) in such a way the two columns are about the same height. I've got insane trying to find the problem in my code and not finding it. It doesn't work for a reason...</p> <pre><code>&lt;body onload="rearrangeImages();"&gt; &lt;div class="images"&gt;&lt;!-- more than one might exist, each with its own figures --&gt; &lt;figure&gt; &lt;figcaption&gt;This is the figcaption of this figure. An image is missing for this test.&lt;/figcaption&gt; &lt;/figure&gt; &lt;figure&gt; &lt;figcaption&gt;This is the figcaption of this figure.&lt;/figcaption&gt; &lt;/figure&gt; &lt;figure&gt; &lt;figcaption&gt;Another one.&lt;/figcaption&gt; &lt;/figure&gt; &lt;/div&gt; &lt;script&gt; function rearrangeImages() { $('.images').each(function() {//should work for each .images independently $(this).prepend('&lt;div class="column_b"&gt;&lt;/div&gt;'); $(this).prepend('&lt;div class="column_a"&gt;&lt;/div&gt;'); $(this).append('&lt;div class="test_div"&gt;&lt;/div&gt;'); $('figure', this).each(function() { var height_a = $(this).parent().$(".column_a").height(); var height_b = $(this).parent().$(".column_b").height(); if (height_a &gt; height_b) { $(this).parent().$(".column_b").append(this); } else { $(this).parent().$(".column_a").append(this); } $(this).remove(); }); }); } &lt;/script&gt; &lt;/body&gt; </code></pre> <p><strong>EDIT</strong> I have found out myself I should use this selector for height a and b:</p> <pre><code>var height_a = $(this).parent().children(".column_a").height(); </code></pre> <p>This is my new jquery:</p> <pre><code>function rearrangeImages() { $('.images').each(function() { $(this).prepend('&lt;div class="test_div"&gt;&lt;/div&gt;'); $(this).prepend('&lt;div class="column_b"&gt;&lt;/div&gt;'); $(this).prepend('&lt;div class="column_a"&gt;&lt;/div&gt;'); $('figure', this).each(function() { var height_a = $(this).parent().children(".column_a").height(); var height_b = $(this).parent().children(".column_b").height(); if (height_a &gt; height_b) { $(this).parent().children(".column_b").append(this); } else { $(this).parent().children(".column_a").append(this); } }); }); } </code></pre> <p>Now I want to extend this function. Pseudocode:</p> <pre><code>if (this is the last figure in .images) { //place last figure in test_div to measure its height; if (height_a &gt; height_b + height_of_last_image) { $(this).parent().children(".column_b").append(this); } else { $(this).parent().append(this); } } else { //do the normal stuff see higher } </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).
