You could use the built-in Listpicker.FilterBar
ShowFilterBar
Returns current state of ShowFilterBar indicating if Search Filter Bar will be displayed on ListPicker or not
alternatively you can use some HTML/jQuery, see this example
Question
I want to implement a searchable list in my Road Safety app for the fines section. Fines will be distinguished based on whether they are parking violations, traffic violations and so on. I found this App Inventor 1 style block for implementing a list filter but it does not work very well. I'd like some help on which blocks to use and how its done.
