I'm working on a smartphone app for searching prices. This is what the menu looks like. In the app, I can switch between the results of "CHEAPEST" and "CLOSEST" without moving away from the main page:
The issue is with the "Filter" to the left (where it says "PREMIUM"): By tapping on "PREMIUM" I can select between "PREMIUM" or "REGULAR". On a website, a regular dropdown (with some CSS to blend) would be the solution. But I don't know if comboboxes exist in smartphone apps.
My question: what native control can I use that will let me select between two values when I tap on something without leaving the current screen? Are there any apps that use this type of control?
IN all the apps I've seen, the filter takes the user to another screen where the selection is made. The problem is that this solution takes me away from the main screen.
