Missing at random

Hi Bryan,
I wanted to try out the procedure you described here but I cannot find the possibility to run HB with "dropped attributes are missing at random". I only find this possibility for dropped levels, not for dropped attributes. Have I overlooked something? Any advice is very welcome!

If an attribute is dropped by using constructed lists, then all levels are set to 0 for that respondent because there is no information about any levels.  The selection of inferior/unavailable/missing at random is just for when some, but not all, levels of an attribute are dropped for a respondent.

Hi Brian,
Thank you for your answer. So Bryan was wrong with his advice? Or is there any other possibility to set "dropped attributes are missing at random"?
I wonder if maybe he meant instead of running it inside of Lighthouse Studio, to use the standalone CBC/HB?  I'll try to follow up with him to clarify, I don't see any settings inside of Lighthouse that allow you to make this choice (meaning set the levels of a missing attribute to zero is just how it behaves).
