I need a new dropdown to be added below the original dropdown when the plus icon is clicked. The container has to respond to that and get bigger to fit both the old container and the new one. The plus icon and its description has to move below the newely created dropdown as well. These actions have to take place as many times as the plus icon is clicked.
In a simplified version of this, I've tried creating an App State Variable and a Page State Variable called containerHeight to expand it on click. I set a default value. I added the variable to the Height parameter and made it so that the value is incremented by some pixels. While in testing mode, the container's initial value is suddenly zero, but gets incremented - from zero. I tried searching info about List View but it seemed like it can be connected to json files, not app state integer variables.
