    <p>I am using two selects, the one as the category and the second one as subcategory. I wish to make the second select menu to be determined by what option was chosen in the second select menu.</p> <p>Here is the html/php code.</p> <pre><code>&lt;select name="category" id="category"&gt; &lt;?php $options = array("Stationary", "Bag", "Paper"); foreach ($options as $option) { echo '&lt;option value"' . $option . '"'; if(in_array($option, $category)){ echo " Selected"; } echo "&gt;" . ucfirst($option) . "&lt;/option&gt;"; } ?&gt; &lt;/select&gt; &lt;select name="subcategory" id="subcategory"&gt; &lt;?php $options = array("Pencils", "Ruler", "Pens"); foreach ($options as $option) { echo '&lt;option value"' . $option . '"'; if(in_array($option, $category)){ echo " selected"; } echo "&gt;" . ucfirst($option) . "&lt;/option&gt;"; } ?&gt; &lt;?php $options = array("Small", "Large", "Paper"); foreach ($options as $option) { echo '&lt;option value"' . $option . '"'; if(in_array($option, $category)){ echo " selected"; } echo "&gt;" . ucfirst($option) . "&lt;/option&gt;"; } ?&gt; &lt;?php $options = array("Notepad", "Plain ", "Colour"); foreach ($options as $option) { echo '&lt;option value"' . $option . '"'; if(in_array($option, $category)){ echo " selected"; } echo "&gt;" . ucfirst($option) . "&lt;/option&gt;"; } ?&gt; &lt;/select&gt; </code></pre> <p>I want it so when and you select one option from category it will it show the correct options to be shown in the <code>&lt;select&gt;</code>. </p> <p>I'm not sure if you can do this, but if anyone has an idea or know how to do this your help would be helpful.</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.
