    <p>I have a multipart form that takes basic user information at the beginning with some jquery.validate error checking to see if the fields have been filled in and the email address is valid.</p> <p>Below that there is a series of check boxes (type_of_request) for new accounts, delete accounts, new software etc which show/hide those form elements as they are checked/unchecked.</p> <p>I would like to validate the required sections on the form ONLY if the corressponding type_of_request item has been checked.</p> <hr> <p>Update information</p> <hr> <p>That's a great solution but seems to make all of the children of the selected section required.</p> <p>A typical scenario will be both the email and other checkbox in the type_request has been selected:</p> <pre><code> &lt;div id="email" style="display: block;"&gt; // shown because other has been selected in the type request &lt;input id="email_new_account" class="sq-form-field" type="checkbox" value="0" name="q4836:q1"/&gt; // not required &lt;input id="email_new_account_name" class="sq-form-field" type="text" name="q4836:q2"/&gt; // if email_new_account checked then make required &lt;input id="email_new_account_access" class="sq-form-field" type="text" name="q4836:q2"/&gt; // if email_new_account checked then make required &lt;input id="email_new_account_manager" class="sq-form-field" type="text" name="q4836:q3"/&gt; // if email_new_account checked then make required &lt;input id="email_add_remove_access" class="sq-form-field" type="checkbox" value="0" name="q4837:q1"/&gt; // not required &lt;input id="email_add_remove_account_name" class="sq-form-field" type="text" name="q4837:q2"/&gt; // if email_add_remove_access checked then make required &lt;input id="email_add_access" class="sq-form-field" type="text" name="q4836:q2"/&gt; // if email_add_remove_access checked then make required &lt;input id="email_remove_access" class="sq-form-field" type="text" name="q4837:q3"/&gt; // if email_add_remove_access checked then make required &lt;/div&gt; &lt;div id="other" style="display: block;"&gt; // shown because other has been selected in the type request &lt;input id="other_describe_request" class="sq-form-field" type="text" name="q4838:q1"/&gt; // required because #other was checked in type request &lt;input id="other_request_justification" class="sq-form-field" type="text" name="q48387:q2"/&gt; // required because #other was checked in type request &lt;/div&gt; </code></pre> <hr> <p>Further Reading</p> <hr> <p>I have reviewed this even further and found that the following can be added to the class of the input items</p> <pre><code>class="{required:true, messages:{required:'Please enter your email address'}}" </code></pre> <p>or</p> <pre><code>class="{required:true, email:true, messages:{required:'Please enter your email address', email:'Please enter a valid email address'}}" </code></pre> <p>but when I add </p> <pre><code>class="{required:'input[@name=other]:checked'}" </code></pre> <p>which was described on the <a href="http://jquery.bassistance.de/api-browser/plugins.html#jQueryvalidatormethodsrequiredStringElementBooleanStringFunction" rel="nofollow noreferrer">http://jquery.bassistance.de</a> site, it doesn't work. Do I need to change the syntax to get this working?</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
