Select2 Select2-Opening event triggers on mobile as soon as control is touched when scrolling
dls...@gmail.com
I am using Select2 version 2.4.6 in a MVC Razor mobile application. My problem is on mobile devices the Select2-Opening triggers as soon as the user starts swiping the screen to scroll if the touch starts on a Select2 control. This causes the dropdown to open which I do not want to happen. I have tried using preventDefault to stop the dropdown action but because the Select2-Opening event is the first event triggered, I have no way of setting any flags to know that I am scrolling to stop the dropdown from opening only while scrolling. Any thoughts or ideas would be greatly appreciated.

This is a common mobile usability issue with Select2, especially on older versions where touch events aren’t handled gracefully. One practical approach is to detect a touchmove event and temporarily disable the Select2 opening until the scroll gesture ends, or bind logic that differentiates between a tap and a swipe based on movement distance. Upgrading to a newer Select2 version (if possible) or handling touchstart/touchend thresholds can also help prevent unwanted dropdown triggers. Similar frontend interaction challenges are often discussed in developer communities and resources like Server

This sounds like a common mobile UX issue with Select2, where the opening event fires too aggressively because touch events are interpreted as intentional clicks while scrolling. On mobile devices, Select2 can’t always distinguish between a scroll gesture and a tap, which causes the dropdown to open unintentionally. A practical workaround is to add a small delay, check for scroll movement before triggering the open event, or disable Select2 on mobile in favor of the native select for better usability. You can find step-by-step fixes and mobile-friendly solutions in detailed Guides that cover Select2 behavior across different devices.
