I'm working on a project that is using the select2 Jquery. I have two drop-down boxes. The second box's options are depends on the first box's selection. So now i want to manually set the value in both boxes.
How can I ensure that the second drop-down box value will only be set when the first drop down box has value and which filtered the second box's options?
