Body
To manipulate an element from JavaScript you need to somehow get a reference to it, which can be done in numerous ways - without any context to go on I'd suggest your best option is to make sure your select element has an <code>id</code> attribute: <pre><code><select id="myDropDown" name="whatever"> <option>One</option> <option>Two</option> </select> </code></pre> ...and then use <code>document.getElementById()</code>. Then to hide it you can update the appropriate style property: <pre><code>document.getElementById("myDropDown").style.display = "none"; // OR document.getElementById("myDropDown").style.visibility = "hidden"; </code></pre> Using <code>display:none</code> causes the browser to render the document as if the element didn't exist, i.e., it won't leave a space for it. Using <code>visibility:hidden</code> will make it invisible but there'll be an empty space on the page. There is more than one way to to test for a particular string on the page, but one way is just to get all the content via the body element's <code>innerHTML</code> or <code>textContent</code> (or, in IE <code>innerText</code>) properties and then use <code>.indexOf()</code>: <pre><code>var searchString = "some string", pageContent = document.body.innerHTML; if (pageContent.indexOf(searchString) != -1) { document.getElementById("myDropDown").style.display = "none"; } </code></pre> Where you place that code depends on when you want to do the test. You could put it in an <code>onload</code> handler if you want to do it without user input, otherwise put it in a click handler or something as appropriate.

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.
