PB 10.5.2, Build 7662

Is there any way to include or simulate a dropdown {
FORMDROPDOWN } or checkbox { FORMCHECKBOX }

in an rtf document in the RTE control?

They 'disappear' when an rtf document created in Word is
loaded into the control.

(This is a user request for which I can find no answer so
far.)

Any ideas will help.
