hello, I'm currently using the dropdowList waterfall. My problem lies in preloading the dropdowList thread. I want to pre-fill the country and the city when the page loads according to the values of my database. for example, Senegal as a country and Dakar as a city.

Thanks in advance and regards,

To pre-fill the country and the city when the page loads, we suggest you use the value property in the control and assign the pre-fill data in that property to select it. We have attached an example for demonstrating your scenario. Please find the sample at the following link
