Need several WIX form drop-down boxes to have the data filtered on the previous drop-down results. I found an example of utilizing a states.jw (??) import tool for states of the United States that is evidently 'built in' to WIX, however, my data is in another WIX database / dataset collection. So, to be clear, the available drop down choices for drop box B is dependent (filtered) based on the results of drop-down A; the available drop down choices for drop box C is dependent (filtered) based on the results of drop-down B. there are only these three dependent drop-downs at the moment.
Any step-by-step instructions would be absolutely fantastic!! <<thanks in advance>>
