Example of dropdown that doesn't spread taint:

local dropdown = CreateFrame("Button", "TestDropdown", parent, "UIDropDownMenuTemplate")
dropdown.text = _G["TestDropdownText"]
dropdown.text:SetText("Default text")
dropdown.info = {}
dropdown.initialize = function(self)
    wipe(self.info)
    for key, value in pairs(dataTable) do
        self.info.text = key
        self.info.value = value
        self.info.func = function(item)
            self.selectedID = item:GetID()
            self.text:SetText(key)
            self.value = value
        end
        self.info.checked = key == self.text:GetText()
        UIDropDownMenu_AddButton(self.info, 1)
    end
end
 
-- get value from dropdown.value
