realizing both flexbox and grid for two-columns of accordions doesn't really work. Best way would be to just divide the amount of things by two, round up, then make a new column.
could not figure out a JS way, which is maybe dumb anyway, but noting it here. Tried appending HTML, but when I try to append </ul><ul> to close then open a new list, the browser always corrects it and assumes what I actually meant was <ul></ul>.
Just did this in PHP instead, works fine. It does make two lists for what is essentially just one, but I don't think that's a gigantic deal.
