keyboards arrow key up and down is not working in invoice to select customer name and account type column how can it work
If you want an answer now, you will have to provide operating system information. Manager version number might also help.
Windows 10 pro
And what version of Manager?
manage ver. 16.3.13
This is a known issue see this post
This issue not yet solved in windows 7 and windows 10
As @lubos advised in the topic referenced above:
The issue is a problem in Select2, a third party component used by Manager. When the issue is fixed in Select2 then it will be fixed in Manager too. So still waiting . . .
