How do AJAX import multiple array files with one loop?

Hello colleagues,

I have 200 array files and each array represents one level configuration.

Since the AJAX request has a file dropdown menu, would that mean I have to make 200 AJAX requests, which seems to me that my approach is wrong, considering that there can be a much higher number of levels than 200, so that would be a lot of request lines.

Is the solution to create an one array, with depth (Z-axis), where the depth would represent the number of levels, so import could be done with a single AJAX request, or is there a better approach to do it, with one loop?

I didn't know that request URL can call array from files.

Thank you very much oosyrag
