    <p>I'm trying to develop a hierarchical menu in my e-commerce website in which my categories are dynamically shown in order to add more categories without having to touch the code.</p> <p>So I've organized my database like that, with 3 different ranks for my categories:</p> <p>I got 3 different ranks:</p> <ul> <li><p><strong>First rank:</strong> Informatics [id=1] Accessories[2] vêtements[3] Hifi ..</p></li> <li><p><strong>Second rank:</strong> Hardware[parent_key=1][id=10] software[parent_key=1][id=11] Men[parent_key=3][id=30] ..</p></li> <li><p><strong>Third rank:</strong> motherboard[parent_key=10][id=100] processor[parent_key=10][id=101] Windows7[parent_key=11][id=110] Shoes[parent_key=30][id=300] ..</p></li> </ul> <p>So you've understood that the "parent_key" refers to the parent id of my category abd for each category of rank 1 I got several rank 2 categories and so on ..</p> <p>For now, I've hard-coded my menu in something like this:</p> <pre><code>&lt;div id="main_menu"&gt; &lt;ul id="nav"&gt; &lt;li class="current"&gt;&lt;a href="&lt;?php echo base_url();?&gt;"&gt;Home&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;High Tech&lt;/a&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;Informatique&lt;/a&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;Hardware&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Ecrans&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Clavier&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Souris&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Imprimantes&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;TV&lt;/a&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;LCD&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Plasma&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;3D&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Appareils Photos&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;GPS&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Smartphones&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Lecteur MP3&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Hi-Fi&lt;/a&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;Amplificateurs&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Enceintes&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Cables&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Autres&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;br class="clear" /&gt; &lt;/div&gt; </code></pre> <p>I'm coding in MVC, and I don't know exactly how to build my model, my controller, and my view. I guess I'll have to do some if/else and foreach loop but I can't figure it out by myself.</p> <p>If anyone wanna help to solve this problem, he is more than welcome :)</p>

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.
