The dependent dropdown will be disabled only if it does not have a list of values (basically empty data source). Check the demo examples - there are dependent dropdowns with pre populated data and enabled for update.

You have two options:

• Ensure the dependent dropdown data is pre-populated with list of dependent values when you are showing the input for update at document load (write code for update scenario to generate the dependent data array).
• If you do not want to generate the data yourself... you can set the initialize property to true in pluginOptions, this will run the ajax request on document load to populate the dependent dropdown.

@akshaybande81 you could pass the param 'selected' in the url with your model->attribute value

'url' => Url::to(['subcat','selected' => $model->myAttribute])
