Fill in the Blanks

Hi. I need to create Fill In The Blanks quiz with multiple blanks along with drop down answers to choose from.

I downloaded H5P, but there is no advance fill in the blank options there, just simple fill in the blank option.

Can you help me out.

Found Advanced Fill In the Blanks which fits my needs. Apparently it's now Complex Fill in the Blanks, not supported by Core. (Why not? it's great!)

Made a nice little content bit for my demo site, but on uploading to Content Bank in Moodle, I'm getting the error:
Missing main library H5P.AdvancedBlanks 1.2

Checked to see if this was on github but no joy.

Any clues, suggestions, or pointers please?

I'm testing theaccessibility of the Advanced Fill in the Blank learning object, and have a few suggestions to improve accessibility. As is it's somewhat accessible, but would be largely unusable with a screen reader.
