Dependent Dropdown With Default Select

jautry · November 26, 2013, 11:08pm

I have a set of dependent dropdowns that work fine if I select each item in the hierarchy. The issue is if I provide a default selected item in the top dropdown, it selects properly, but does not create the ajax actions to cascade down to the rest of them. What is the best way to make this happen?

echo CHtml::dropDownList(‘id_category’, $findCategory, $categories, array(‘prompt’=>’—Select—’,

                                                    'ajax'=&gt;array(


                                                    'type'=&gt;'POST',


                                                    'url'=&gt;yii::app()-&gt;createUrl(asset/AssetTypeData'),


                                                    'data'=&gt;array('category'=&gt;'js:jQuery(this).val()'),


                                                    'update'=&gt;'#id_types',


                                                    )));

echo CHtml::dropDownList(‘id_types’, $findType, $findTypeArray, array(‘prompt’=>’—Select—’,

                                                   'ajax'=&gt;array(


                                                   'type'=&gt;'POST',


                                                   'url'=&gt;yii::app()-&gt;createUrl('asset/AssetAttributeData'),


                                                   'data'=&gt;array('type'=&gt;'js:jQuery(this).val()'),


                                                   'update'=&gt;'#assetGrid',


                                                   )));

etc.
