    <p>I have a form. I want to disable or enable a drop down depending on a radio button selection. I need to do this several times in the form. I am new to Javascript so I dont really know where to start. this is a part of the form:</p> <pre><code>&lt;p id="hospitalorientation"&gt;&lt;label&gt;Hospital Orientation:&lt;/label&gt; &lt;div id='buttons'&gt; &lt;label&gt;&lt;input type="radio" name="hospital" /&gt; Not Complete &lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="hospital" /&gt; Complete &lt;/label&gt; &lt;/div&gt; &lt;div id="list1" style="display: none;"&gt; &lt;label&gt;Month Complete: &lt;select&gt; &lt;option&gt;January&lt;/option&gt; &lt;option&gt;February&lt;/option&gt; &lt;option&gt;March&lt;/option&gt; &lt;option&gt;April&lt;/option&gt; &lt;option&gt;May&lt;/option&gt; &lt;option&gt;June&lt;/option&gt; &lt;option&gt;July&lt;/option&gt; &lt;option&gt;August&lt;/option&gt; &lt;option&gt;September&lt;/option&gt; &lt;option&gt;October&lt;/option&gt; &lt;option&gt;November&lt;/option&gt; &lt;option&gt;December&lt;/option&gt; &lt;/select&gt; &lt;/label&gt; &lt;/div&gt; </code></pre> <p>and then i have basically several replicas of this in the form..</p> <pre><code>&lt;p id="ppd"&gt;&lt;label&gt;PPD:&lt;/label&gt; &lt;div id='buttons'&gt; &lt;label&gt;&lt;input type="radio" name="ppd" /&gt; Not Complete &lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="ppd" /&gt; Complete &lt;/label&gt; &lt;/div&gt; &lt;div id="list2" style="display: none;"&gt; &lt;label&gt;Month Complete: &lt;select&gt; &lt;option&gt;January&lt;/option&gt; &lt;option&gt;February&lt;/option&gt; &lt;option&gt;March&lt;/option&gt; &lt;option&gt;April&lt;/option&gt; &lt;option&gt;May&lt;/option&gt; &lt;option&gt;June&lt;/option&gt; &lt;option&gt;July&lt;/option&gt; &lt;option&gt;August&lt;/option&gt; &lt;option&gt;September&lt;/option&gt; &lt;option&gt;October&lt;/option&gt; &lt;option&gt;November&lt;/option&gt; &lt;option&gt;December&lt;/option&gt; &lt;/select&gt; </code></pre> <p> </p> <p>And now I dont really know where to go from there.</p>

    1. COWhy not start with a javascript framework that will allow you to do this with relative ease. jQuery is one of the most popular JS frameworks: http://jquery.com/

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).
