    <p>There are any number of different ways to skin this particular cat, some more efficient than others. Below is off the top of my head and meant to get you headed in the right general direction.</p> <p>In addition to your <code>$category_link</code> you need something that indexes your subcategories by category. Something like <code>$subcategory_link</code> which might be an array of arrays, indexed first by the category id (or name), and then by an incrementing integer for each subcategory (or its id, or whatever). In addition to your existing query and <code>while</code> loop, run a query that retrieves all of the subcategories, and then fills in <code>$subcategory_link</code> with the relevant information in a second, similar <code>while</code> loop.</p> <pre><code>$sc = array( 'id' =&gt; $subcategory['id'], 'subcategory' =&gt; $subcategory['subcategory'], ); $subcategory_link[$subcategory['cat_id']][$j++] = $sc; </code></pre> <p>Note that this array is first indexed by the category id. Then in your template:</p> <pre><code>{foreach $category_link as $cat} &lt;div class="category"&gt;{$cat.catname}&lt;/div&gt; {foreach $subcategory_link[$cat.cat_id] as $subcat} &lt;div class="subcat"&gt;{$subcat.subcategory}&lt;/div&gt; {/foreach} {/foreach} </code></pre> <p><em><strong>Note</em></strong>: The above has not been checked for proper Smarty syntax. You should get the idea though.</p> <p>It is left as an exercise for you to determine how to handle categories with no subcategories, and to improve efficiency.</p>

Guidance
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.
