Can you provide a code sample that somehow explains what you're trying to achieve?

[bnadem]

class TestCase {

public : constexpre frozen:.unordered_map<std::string, item_t> itemnotification;
}

im Constructor i want to initilise data, count of Data is defined from Outside

The following is possible and should match your needs. Note that the size of the unordered_map must be fixed (or a template parameter of the class)

#include "frozen/string.h"
#include "frozen/unordered_map.h"
#include <iostream>

struct F {
  const frozen::unordered_map<int, int, 3> member;
  constexpr F(int x, int y, int z) : member{{x,y}, {y,z}, {z, x}} {}
};


int main() {
  constexpr F f(1,2,3);
  std::cout << "Map size: " << f.member.size() << "\n";
  for(auto const& kv: f.member)
    std::cout << kv.first << ": " << kv.second << "\n";
  return 0;
}
