Please do not kick with your feet, the problem can be solved already, but I can’t find it.
Although something like this jumped jquery-select-hierarchy-master, but not that.
The essence is that there is a select with makes and models of cars, for example. But in one it is overwhelmed very bulky.
Is it possible to somehow develop it in jquery into 2 hierarchical selects like here autostan.kz? that is, we choose BMW and models appear in the second selection - 320, 520, 630, and so on
