copied!<p>You're correct that ZF 1.8 doesn't support grouping of options in this way. You could easily look at the code inside <code>Zend_View_Helper_FormRadio</code> and create your own view helper that supports a multi-dimensional array (ie the select groupings). I had to do this already for a project, check out the example at <a href="http://pastebin.com/f1dd448e3" rel="noreferrer">pastebin.com</a></p> <p>PHP:</p> <pre><code>$form->addElement('radio', 'test', array( 'helper'=>'formMultiRadio', 'label'=>'Test Thing', 'multiOptions'=>array( 'Test'=>array('1'=>'1', '2'=>'2'), 'Test 2'=>array('3'=>'3', '4'=>'4'), 'Test 3'=>array('5'=>'5', '6'=>'6'), ), )); </code></pre> <p>Resulting HTML:</p> <pre><code><dt id="test-label"><label for="test" class="optional">Test Thing</label></dt> <dd id="test-element"> Test<br /> <label for="test-1"><input type="radio" name="test" id="test-1" value="1" />1</label><br /> <label for="test-2"><input type="radio" name="test" id="test-2" value="2" />2</label><br /> Test 2<br /> <label for="test-3"><input type="radio" name="test" id="test-3" value="3" />3</label><br /> <label for="test-4"><input type="radio" name="test" id="test-4" value="4" />4</label><br /> Test 3<br /> <label for="test-5"><input type="radio" name="test" id="test-5" value="5" />5</label><br /> <label for="test-6"><input type="radio" name="test" id="test-6" value="6" />6</label> </dd> </code></pre>
