According to the id on the selected dropdownlist, the other dropdownlist is not listed as we want.

Question

We want the data we select from Dropdownlist to come according to the "id" of the other dropdownlist. We tried it in cascade structure, but did not get any results. API can display the way we want to brand.

Hi Aykut, 
  
Greetings from Syncfusion support. 
  
We have implemented the cascading action in the DropDownList component based on the other DropDownList component’s value.
