I am analysing feathery for my client project. I loved the ease of configuring forms that feathery provides.  
The form I need has 8 dropdowns but the list of dropdown values changes based on the selection of the previous dropdown field.  
eg, Selecting a value in the first dropdown changes the values in the next 7 dropdowns, selecting a value in the second dropdown changes the values in the next 6 dropdowns and so on.  
Is there a way I can configure this on feathery?

The APIs make the form feel more slower, especially in poor connectivity. Is there a way I can load a lookup and the form could lookup the necessary values for the option list?
