Add Child to description popup field.
- 
 Hello. I am creating a parameter description with a popup field but I can not add childs to it. I know that in a GeDialog it is very straightforward AddChild(pop_up_ID,id,name). 
 Also I managed to add child to a CycleButton CustomGui and I thought it would be very similar to this.BaseContainer bc = GetCustomDataTypeDefault(DTYPE_LONG); bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_CYCLEBUTTON); bc.SetString(DESC_NAME, "Cycle Button"); bc.SetContainer(DESC_CYCLE, settings); return dc->SetParameter(DescLevel(id, DTYPE_LONG, 0), bc, group_id);where settings is the container that contains the item names for the cycle. 
 What would be the equivalent of this for a popup field?
 I have tried some options but none of it worked. Also DESC_CYCLE would not work for the items of an popup field.BaseContainer bc = GetCustomDataTypeDefault(DTYPE_POPUP); bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_POPUP); //bc.SetString(DESC_NAME, "Pop Up Button"); //bc.SetContainer(DESC_CYCLE, settings); return dc->SetParameter(DescLevel(id, DTYPE_POPUP, 0), bc, group_id);Thank you.

 I found the solution. Seems that I had to use MSG_DESCRIPTION_POPUP message to fill the popup field.

 hello, Are you creating your own custom parameter of using an existing one ? Cheers

 Hello. I am creating my own custom parameter.

 hello, So yes, you have to react to MSG_DESCRIPTION_POPUP, you can see an example on the nodedata manual I thought first you wanted to create a popup menu. Cheers,
