I am creating my travel packages website. Now i have a dataset cities which has City list of various countries. This set has the following fields. I want a Dropdown which list all countries from this set to be listed. Once the user selects a Particular Country ( say france ) and click “Add”, it should show all cities in france in checkbox and allow user to select the cities they wish to travel to and submit this info to my email so that i can customize the pacakage depending on their selection.
i am not a coder, so i dont know how to do this. can someone help me out with this bit
