As shown in the picture: Just this kind of second-level linkage, I am looking for ideas... I don’t know how to write... It was developed using bootstrap and jquery.
There are two drop-down menus, but the drop-down menus in bootstrap are used without select and option tags.
Waiting online...Urgent! ! !
