Microsoft Edge drop-down menu does not stay

Question

In Microsoft Edge on Windows 10, when I tap on drop down menus, they won't remain for long. For example, in eBay when, I tap on my eBay drop down, it is shown only for few seconds and goes away very quickly.

ok I found the problem , its because the websites I tested are not fully compatible with windows tablet mode in windows 10 using Microsoft edge , so , eventually they are going to update themselves and this problem wont occur again , I tried with some other websites like Microsoft itself and intel and dropdowns was just fine ,

Answer 2
