Hello,

When building an HDA, I will often promote parameters from nodes inside by dragging the child node's parameters into the "Edit Operator Type Properties" dialog, but I'm running into a case where I can't do that. In LOPs, I'll often come across an icon button that has options such as "Do Nothing", "Set or Creation", "Set if Exists", etc., but if I try to drag and drop it the same way, it'll just open up the menu instead. It feels a bit silly that I can't figure this out, but how can I easily promote these parameters to the HDA? Have a look at the attached screenshot to see what I mean.

click on From Nodes Tab and do it from there
you can multiselect many parameters and click right arrow icon

You should probably report this as a bug tho. Almost certainly unintended behavior.

alt-MMB on a parm does the same, maybe that will work in this case.

Thanks for the answers everyone! Exactly what I was looking for.
