    <p>I'm trying to build a directive that takes care of <strong>adding more directives</strong> to the element it is declared on. For example, I want to build a directive that takes care of adding <code>datepicker</code>, <code>datepicker-language</code> and <code>ng-required="true"</code>.</p> <p>If I try to add those attributes and then use <code>$compile</code> I obviously generate an infinite loop, so I am checking if I have already added the needed attributes:</p> <pre><code>angular.module('app') .directive('superDirective', function ($compile, $injector) { return { restrict: 'A', replace: true, link: function compile(scope, element, attrs) { if (element.attr('datepicker')) { // check return; } element.attr('datepicker', 'someValue'); element.attr('datepicker-language', 'en'); // some more $compile(element)(scope); } }; }); </code></pre> <p>Of course, if I don't <code>$compile</code> the element, the attributes will be set but the directive won't be bootstrapped.</p> <p>Is this approach correct or am I doing it wrong? Is there a better way to achieve the same behavior?</p> <p><strong>UDPATE</strong>: given the fact that <code>$compile</code> is the only way to achieve this, is there a way to skip the first compilation pass (the element may contain several children)? Maybe by setting <code>terminal:true</code>?</p> <p><strong>UPDATE 2</strong>: I have tried putting the directive into a <code>select</code> element and, as expected, the compilation runs twice, which means there is twice the number of expected <code>option</code>s.</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.
