Hi, Good Day to all.
Please kindly help I also encounter the same problem on flexigrid theme. The dropdown multiselect is not showing the actual records of the selection list. Only the add all and remove all button appear on mobile devices(Iphone 5s, ASUS Zenfone 3 Max 5.5 with all browsers safari, chrome etc...)
but on Desktop and Laptop browsers its working without any problem.
This is a very good framework.
