| Jul 28, 2016 at 11:26 | comment | added | Emad Kerhily | oh thanks @4k4 it works perfectly, but I want some more help which is I want to fill in the level2 select with options. those options I retrieve from database in my controller function named getTermChild($termid) which return array of retrieved children what I did is: ` $val = $form_state->getValue('level1'); $terms = $controller->getTerms($val); $form['ajax_wrapper']['level2']['options'] = $terms; return $form['ajax_wrapper']; ` but still the select is empty | |
