Is it possible to hide a document from Adobe FrameMaker 2015?

Ch,

You can open it hidden with the FDK or ExtendScript, something like:

  F_PropValsT openScript, *returnp = NULL;
  UIntT sn;

  F_ObjHandleT docId;

  openScript = F_ApiGetOpenDefaultParams();
  sn = F_ApiGetPropIndex(&openScript, FS_MakeVisible);
  openScript.val[sn].propVal.u.ival = True;
  docId = F_ApiOpen("C:\\SomePath\\SomeDoc.fm", &openScript, &returnp);

You can also make a currently-open document hidden:

F_ApiSetInt(FV_SessionId, docId, FP_IsOnScreen, False);

There isn't any way to do it through the GUI.
