I need to create a landing page collect prospect data. In the page I have to create to drop down menus (HTML: Select). The first one is to select car brand and the second one to select the model of the brand.
I have a data extension with all brands and models, the data extension is monthly updated. The challenge I have is that I do not know how to make that the second drop down only displays the models of the brand selected in the first select component.
Thanks for any help.
