Which items from the palette can I use?

WEB TMS WEB Core

As I tried to use a FDMemTable in WEbCore form (which fails at compile time) with :can't find unit "FireDAC.Stan.Intf", I am unsure what entries from the palette I may use.

Why is TFDMemTable shown, but must not be used?
Would it be possible to use eg a TClientdataset, but create it at runtime?
What are the restrictions in using other units?

tx for an answer.

BTW: It really is an awful feeling to write Delphi code an have it run in the Web. :- )

Everything from "TMS WEB*" tabs on the tool palette.

We could not find a way to make the Delphi IDE exclude non TMS WEB Core non-visual components.
