RE: want to add all arrays,

There seem to be some assumptions here you're not stating. Is the ordering / length of the 3 arrays expected to always be matching / consistent? I.e. the first entry in the "countries" array will always match the first one in "states" and likewise with "languages", etc?

If so, it seems like your initial setup might be improved (if possible) - instead of a random assortment of arrays, why aren't we starting out with a list of dictionary / CDT / map, with structured data? i.e.

local!dataList: { a!map(country: "USA", state: "Texas", language: "English), a!map(country: "China"....), ... },

That'd make it quite a bit more straightforward to display the info you want to have displayed, without the necessary guesswork and (imho) sloppy merge() operations necessary.
