    <p>I created the following form: <a href="http://jsfiddle.net/baumdexterous/GYNSu/1/" rel="nofollow">http://jsfiddle.net/baumdexterous/GYNSu/1/</a></p> <p>I implemented a validation script that works for many of the form elements but for some reason it's not working for the radio buttons so currently a user can submit the form without selecting one of the required radio buttons. </p> <p>How can I enable validation for the radio buttons using this existing script? Thanks so much.</p> <pre><code> &lt;ul&gt; &lt;li class="required"&gt; &lt;label&gt;What is the U.S. Capital? Please select your answer below:&lt;/label&gt; &lt;div class="questionsone"&gt; &lt;input name="questionone" type="radio" value="a"&gt;a) New York&lt;br&gt; &lt;input name="questionone" type="radio" value="b"&gt;b) Washington DC&lt;br&gt; &lt;input name="questionone" type="radio" value="c"&gt;c) Seattle&lt;br&gt; &lt;input name="questionone" type="radio" value="d"&gt;d) Portland&lt;br&gt; &lt;/div&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p><strong>Update</strong>: I have this JavaScript part that works with the existing validation. Trying to figure out how to add a way that will detect radio buttons:</p> <pre><code> &lt;script&gt; $(function() { var root = $("#wizard").scrollable(); // some variables that we need var api = root.scrollable(), drawer = $("#drawer"); // validation logic is done inside the onBeforeSeek callback api.onBeforeSeek(function(event, i) { // we are going 1 step backwards so no need for validation if (api.getIndex() &lt; i) { // 1. get current page var page = root.find(".page").eq(api.getIndex()), // 2. .. and all required fields inside the page inputs = page.find(".required :input").removeClass("error"), // 3. .. which are empty empty = inputs.filter(function() { return $(this).val().replace(/\s*/g, '') == ''; }); // if there are empty fields, then if (empty.length) { // slide down the drawer drawer.slideDown(function() { // colored flash effect drawer.css("backgroundColor", "#229"); setTimeout(function() { drawer.css("backgroundColor", "#fff"); }, 1000); }); // add a CSS class name "error" for empty &amp; required fields empty.addClass("error"); // cancel seeking of the scrollable by returning false return false; // everything is good } else { // hide the drawer drawer.slideUp(); } } // update status bar $("#status li").removeClass("active").eq(i).addClass("active"); }); // if tab is pressed on the next button seek to next page root.find("button.next").keydown(function(e) { if (e.keyCode == 9) { // seeks to next tab by executing our validation routine api.next(); e.preventDefault(); } }); }); &lt;/script&gt; </code></pre>

    1. COYou should keep the names the same for those radio buttons, otherwise you can select all of them at once. Keeping the name the same ensures that at most one of the radio buttons can be checked.

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.
