Chain select with category and sub category in CodeIgniter

Question

How to create a dropdown select menu in CI so that if I select a category, a sub category will appear on the same page without refreshing the browser?

Answer 1

You should do it via AJAX and retrieve the subcategories. Have a ready subcategories or dropdown.

Append the values return by PHP into the dropdown.

Some pseudo-code:

$.each(data, function(key, value)
{   
     $('#subcategories').
          append($("").attr("value",key).text(value)); 
});
