how can I filter within a form a server-side call for options of a richtselect element. I have to filter the items that have a certain id.
For example project_id … “data / data_tag.php? Idprogetto = project_id”
{id: “id_tag”, editor: “richselect”, header: “Associate TAG”, vertical: true, options: “data / data_tag.php”, fillspace: 1},
thank you
