You’re probably looking for entity-attribute-value.

Here’s an extension that claims to support it.

Alternatively, you could look into using a non-relational database such as MongoDB.

I was caught with a requirement same as you told have category, subcat and type in parent child relation to manipulate form fields to display user.

What I did is, loaded the full form with all the fields and than on change event of subcat called a JQuery that manipulate the form and show only the related fields to user its easy to manage in this way as on submit Yii leave the blank fields while adding or updating a model. for quick you may create an array that reflect the fields to show in catrgroies array(‘alpha’=>array(1.2), ‘beta’=>‘2,3’) and loop through the array in the js to hide or show fields.

or you can load the form with renderPartial() using ajax on the page.

if you need some code to more elaborate what I said let me know.

May I know where exactly you have problem?? controller or view?? and which code sample you need js?? check the following

var fieldsToShow = new Array();

                    var fieldIds = new Array('3','4','6','10','14','16','18','19','20','21','22','23','304','305', '306','307','308','309','310','311','312','313');


                    for(var j=1; j<fieldIds.length ; j++) {  


                     fieldsToShow["'"+fieldIds[j]+"'"] = new Array();


                    }

fieldsToShow[‘3’] = Array(’_country_id’, ‘_city_id’, ‘_manufacturar’,’_production_year’, ‘_length’, ‘_capacity’ );

fieldsToShow[‘anyindex’] = Array(‘your fields’);

and than may use switch case

switch (dropdownVal) {

                        case ( "3" ): //offshore marien vesles and boats


                                    var fieldsToShowArray = fieldsToShow['3'] ;


                                    


                                    for(var i =0; i<fieldsToShowArray.length; i++){


                                       


                                         $('#'+pagename+fieldsToShowArray[i]).closest('.col-md-6').toggle();


                                         


                                         $('#'+pagename+fieldsToShowArray[i]).closest('.col-md-3').toggle(true);


                                         


                                          $('#'+pagename+fieldsToShowArray[i]).closest('.form-group').toggle(true)


                                         


                                         


                                         


                                         


                                    }





                                    break;
