You need to create a PRM_ChoiceList() that takes a callback function to generate the list of attributes. Look here for an example that does this with groups: http://www.sidefx.com/docs/hdk13.0/hdk_opbasics_overview_parameters.html#HDK_OpBasics_Overview_Parameters_Menus

Whether the rop nodes can also such operations ?

static void
sopBuildRestGroup(void *data, PRM_Name *choicenames, int listsize,
const PRM_SpareData *spare, PRM_Parm *parm)
{
SOP_Node *sop = CAST_SOPNODE((OP_Node *)data);

if( sop )
{
sop->buildInputGroups( SOP_REST_INPUT, choicenames, listsize,
PRIM_GROUP, 0, true, parm );
}
else
{
choicenames[0].setToken(0);
choicenames[0].setLabel(0);
}
}

static PRM_ChoiceList sopRestGroupMenu(PRM_CHOICELIST_TOGGLE,
sopBuildRestGroup);

 

 

I copied the code in my code
The result error:

error C2664: “PRM_ChoiceList::PRM_ChoiceList(PRM_ChoiceListType,PRM_Name *)”: Parameters 2 can not be 

“void (__cdecl *)(void *,PRM_Name *,int,const PRM_SpareData *,PRM_Parm *)”convert to“PRM_Name *”

ROP_Node's have no geometry so the question doesn't make sense. If you have a SOP_Node handy, then you can get the attributes from it.

 

The last parameter to sopBuildRestGroup() is missing const.
