Creating Dynamic Dependent Dropdown Boxes Using jQuery/AJAX with PHP/MySQL
Aiming to create a dynamic set of dropdown boxes, you attempt to use jQuery/AJAX and PHP/MySQL.

$.each(data.subjects, function(i, val){
$('select#item_2').append(`<option value="${val.id}">${val.name}</option>`);
});Additional Considerations:
