@russian-dima Thanks for that re-ordering, and particularly for the adding multiple items to .collapse, .hide etc lines - didn’t realise you could do that 
However, I’m not sure there is a bug in this code as from what you have said previously I need to use wix-storage to enable the dropdown selections to remain and to avoid the dropdown’s resetting but is it possible to setItem and getItem all within the same code for a dynamic page?
