Populate second drop-down on the basis of value selected in First Dropdown

[Veena_Vikram]

I've requirement to populate second drop down on the basis of value selected in first dropdown.

The catch here is list for both the drop-down is dynamic, I've to fetch it from back-end.

I need to implement this in AEM component.

Kindly suggest @Arun_Patidar  @Veena_Vikram @Theo_Pendle

As @Arun_Patidar  mentioned, you should use the json and fill the drop down list.

You can get help of this page as well.

This Dynamic drop down List will not save the previous selected value by reopening the dialog box. If you want to save it you should use “.selecteditem” as you see in the link which I attached.

You can create the first dropdown as dynamic based on datasource. Second dropdown you have to populate based on on select event of option of first dropdown.

Long back I created a POC solution where second dropdown populated with the children pages based on selected page in first dropdown(pathbrowser in my example)

@HalehHaerian  could you please guide here as you adapted this solution for dropdowns.
