With .SD:

This would be easier with a defaultdict, but you can do it without any imports.

To use lists as values:

There are some mistakes, complications and missing things in your code.

The following will display a functional dropdown filter based on the shipping state location on admin order list (based on shipping settings allowed countries/states):

strarr is an array of pointers to char, but string is not an array of pointers but an array of 14-element array of chars.

Pointers and 14-element array of chars may have different size, so your code won't work well.

How about using array of pointers like this?

Use the fetch API and the power of promises:

The problem lays in the two calls to malloc(sizeof(strarr)). The variable strarr is a pointer to a string, not the string itself which has not been allocated. The size of strarr is just sufficient to contain one address, or few characters, but normally not an entire string. So you are using a random part of the memory for storing the end of your string.

If you maintain your code more or less as it is, you will need to know how long the resulting longest string will be for allocating it with malloc(sizeof(char) * max_length_returned).
