How to realize the menu search function?

like this

I would use some custom class like this:

class Settings {
  public:
    Settings() {
        Initialize();
    }

    void AddCheckbox(const std::string& label, bool* value_ptr) {
        checkboxes_.push_back(std::make_tuple(label, value_ptr));
    }

    void AddSliderInt(const std::string& label, int* value_ptr, int min_value, int max_value, const std::string& format) {
        slider_ints_.push_back(std::make_tuple(label, value_ptr, min_value, max_value, format));
    }

    // Predicate (you can change it to fit your requirements)
    bool IsStringFitQuery(const std::string& query, const std::string& str) {
        return std::search(str.begin(), str.end(), query.begin(), query.end(),
            [](char lhs, char rhs) { return std::toupper(lhs) == std::toupper(rhs); }) != str.end();
    }

    // Method, that finds acceptable settings and "draws" them
    void DrawSettingsThatFitQuery(const std::string& query) {
        for (const auto& checkbox_args : checkboxes_) {  // Or you can use structured binding here, if it's more comfortable for you
            if (IsStringFitQuery(query, std::get<0>(checkbox_args))) {
                ImGui::Checkbox(std::get<0>(checkbox_args), std::get<1>(checkbox_args));
            }
        }

        for (const auto& slider_int_args : slider_ints_) {  // Or you can use structured binding here, if it's more comfortable for you
            if (IsSettingFitQuery(query, std::get<0>(slider_int_args ))) {
                ImGui::Checkbox(std::get<0>(slider_int_args), std::get<1>(slider_int_args), std::get<2>(slider_int_args), std::get<3>(slider_int_args), std::get<4>(slider_int_args));
            }
        }

        // etc.
    }

  private:
      void Initialize() {
        AddCheckbox("Findable Bool", &findable_bool);
        AddCheckBox("Also Findable Bool", &also_findable_bool);
      
        AddSliderInt("Findable Int", &findable_int, 1, 100, "%d ints");
        AddSliderInt("Also Findable Int", &also_findable_int, 1, 420, "%d ints here");
    }

    // Vectors holding "findable" settings
    std::vector<std::tuple<std::string, bool*>> checkboxes_;
    std::vector<std::tuple<std::string, int*, int, int, std::string>> slider_ints_;
    // etc.
  
    // Settings data
    bool findable_bool{true};
    bool also_findable_bool{false};
  
    int findable_int{1};
    int also_findable_int{69};
  
    // You can also have some settings that will be "unfindable"
    bool unfindable_bool{false};
    int unfindable_int{0};
    // etc.
};

Code has enough comments to understand how does it work, so if you understand modern c++ and imgui at least a bit more than a beginner you should understand how to use it. Otherwise I spent my time for nothing :(

P.S. I wrote it without even compiling, because I am lazy. But again, if you are not a complete beginner you can fix possible errors
