I'm  really new in jquerry and i'm having difficulties figuring out how to disable a drop down list by id when a checkbox is checked. 

The logic would look like this. 

1) If a checkbox is enabled (checked) then disable drop down

2) If a checkbox is disabled (unchecked) then enable the drop down

The checkbox id for example is Trivial_Order and the Dropdown id is manager_search

I just can't figure out how to implement this checkbox logic in this code. 

Could anyone please help?
