I have a list that contains list of properties. the property categorized with column category:
column category has either House or Apartment value.
I use vertical gallery to display the list.
the value of Items for the gallery is:
SortByColumns(Filter(propertylist,category.Value=Dropdown1.SelectedText.Value), "posteddate", SortOrder.Descending)
the drop-down items value: ["House","Apartment"]

This gallery displays the list of house or Apartments at a time, now i want to add All into thee drop down, so that by default the list will be all lists of houses and Apartments. expected drop down options "All","House","Apartments". when I choice All, get list of both houses and apartments.
how can i do that?
the column category in SharePoint list is a type choice with House,Apartment.
your help is appreciated.
