Hi Guys,


It's a great library..


I have some problem, the second select list is updated but it's still disabled.. 


The select option is updated accordingly, however the JQuery Chosen is still disabled and it's not populated..


I wonder if someone has similar situation

Hi, I'm a newbie to GC and I have managed to install it successfully. Now I'm trying to add the dependent select box with this library. I'm getting values in the country dropdown, but state and city dropdowns seem to be disabled. I think I'm having issues with including js files, please find attached files. Also, I have created the foreign key between tables country, state and city.


Pasting the controller function 


public function locs_management()
$crud = new grocery_CRUD();
$fields = array(
// first field:
'con_id' => array( // first dropdown name
'table_name' => 'country', // table of country
'title' => 'name', // country title
'relate' => null // the first dropdown hasn't a relation
// second field
'st_id' => array( // second dropdown name
'table_name' => 'state', // table of state
'title' => 'st_name', // state title
'id_field' => 'id', // table of state: primary key
'relate' => 'con_id', // table of state:
'data-placeholder' => 'select state' //dropdown's data-placeholder:
// third field. same settings
'ct_id' => array(
'table_name' => 'city',
//'where' =>"post_code>'167'",  // string. It's an optional parameter.
//'order_by'=>"state_title DESC",  // string. It's an optional parameter.
'title' => 'id: {id} / city : {ct_name}',  // now you can use this format )))
'id_field' => 'city_id',
'relate' => 'st_id',
'data-placeholder' => 'select city'
$config = array(
'main_table' => 'locations',
'main_table_primary' => 'id',
"url" => base_url() . __CLASS__ . '/' . __FUNCTION__ . '/', //path to method
//'ajax_loader' => base_url() . 'ajax-loader.gif' // path to ajax-loader image. It's an optional parameter
//'segment_name' =>'Your_segment_name' // It's an optional parameter. by default "get_items"
//print_r ($crud);
        //print_r ($fields);
        //print_r ($config);
$categories = new gc_dependent_select($crud, $fields, $config);
$js = $categories->get_js();
$output = $crud->render();
$output->output.= $js;


Thanks in advance.
