I am new to QLIK sense mashup and would like to create a web application where all the filters will be replaced by custom dropdown boxes ( don't know why but the business just asked for it).
I am able to create two dropdown lists. one for customer and other for carrier and I can successfully populate the data in both the dropdown boxes.
However, the next thing I would like to do is to, upon selecting One or multiple Customers from customer dropdown list, I want my carrier drop down list to show only carriers which the selected customers are using and do not want to show the full list of carriers.
How do I achieve that using QLIK Sense Mashu APIs. I used below link to create two dropdown boxes with data loaded so far. Please provide some sample code if possible.
