Dynamic chnage on List from chnage on DropDown(ComboBox)

[rajee Malar]

I need to create one dropdown(conmbo box) and one list.
When there is a chnage in a dropdown, list values should change dynamically.
For example, dropdown will have list of auto manufacturers (like Honda, Toyota, Mazda)
So if I select Toyota on the DropDown the list will say (Camry, Corolla, 4 runner, Land Cruiser). All these datas are in the database.

Please help me on this.
