Displaying ActiveForm fields?

Question

Yii

There is a model and a form, on the form there is one dropdown with selection options (and each requires its own set of model fields). What can be done to solve it?

Answer 1

JS (jQuery). We listen to the change event in the select, then several options:
- ajax request, getting the necessary form fields (html + js via ->renderAjax()
- the fields are already in a separate block, we just hide and show the blocks
- there is a config in the form of json, it contains field selectors, which should be shown when the option is selected.
There is also a simple, but not userFrandly option, when changing the select results in a get request with a parameter, which simply regenerates the page. But if there are problems with js, this option may turn out to be simple.
