Changing Display columns depending on sourcetype

In Dashboard depending on sourcetype selected in the dropdown list, we want to display different fields on the dashboard. Since fields can change in the future we have created a lookup for it. So depending on source type the lookup should be queried and get the display columns. I am trying something like below but doesn't seem to work index=nirds sourcetype="XXX"|table [|inputlookup SourceType-Attributes sourcetype="XXX" | fields Attribute]
