What you want is the second dropdown to react on the first and on the occassion that there is just one result in the second combobox you want to auto select this result. To do this do the next:
ShowColumns(Filter(DropDown2,C1 = ComboBox1.Selected.Value1),"C2","C1")
If(CountRows(Filter(DropDown2,C1 = ComboBox1.Selected.Value1)) = 1,First(Filter(DropDown2,C1 = ComboBox1.Selected.Value1)))
Basically you take the same filter formula from the Items part and count the rows. When this is 1 then you take the first record from the filter and set this as default. When it is not 1 then this part is in fact just false, like as you dont set a defaultselected item.
On the label (or textbox default) you can do a few things, like:
ComboBox1.Selected.Value1 & " - " & Coalesce(ComboBox1_1.Selected.C2)
Or when you don't want the minus sign to be visible this:
ComboBox1.Selected.Value1 & If(!IsBlank(ComboBox1_1.Selected.C2), " - " & ComboBox1_1.Selected.C2)
Unfortuately there is no [Combobox].CountItems on this moment, this would make this a lot easier. On the idea board there is a threat off mine on this topic, maybe you can give this kudos?
Hope this works for you.
