I am working on WAB developer edition 2.5 in query widget I want to add some customization. I am not sure it is possible. I have attached the screen shot which shows the Hurricane Evacuation Zone where is zones can be 3 or more in drop down. I can select each time one such as A, B, or C. If I want to select A and B or all how can add the check button here in Query filter? Is it possible to have check button here instead of drop down? So that user can select more than one. I am sorry I am new to WAB and trying to learn.
I really appreciate any help!
