In this post, I would like to show you data populating in select 2 dropdown based on x event and it will get data from the remote server using Http protocol, the same technique you can apply for dependent dropdowns to show data based on the selection.
Populate Select2 with AJAX data example
In the following exmple we are loading data on page load and appending data to select dropdown, same technique you can apply with any avaliable javascript events like click, change ..etc.
