**Ini kode saya:**

document.addEventListener("DOMContentLoaded", function() {
    const header = document.querySelector(".header");
    const langSelect = document.querySelector("#lang_select");
    const langList = document.querySelector(".lang_list");

    header.addEventListener("click", function(event) {
      langList.style.display = langList.style.display === "none" ? "block" : "none";
      event.stopPropagation();
    });

    document.addEventListener("click", function(event) {
      if (!langSelect.contains(event.target)) {
        langList.style.display = "none";
      }
    });

    const fieldInputs = document.querySelectorAll(".field input");

fieldInputs.forEach(function(input) {
  input.addEventListener("focus", function() {
    this.parentElement.classList.add("active");
  });

  input.addEventListener("blur", function() {
    if (this.value === "") {
      this.parentElement.classList.remove("active");
    }
  });
});

let isFirstOpen = false;
  const firstBtn = document.querySelector("#firstBtn");
  const firstDrop = document.querySelector("#firstDrop");

  firstBtn.addEventListener("click", function(event) {
    isFirstOpen = !isFirstOpen;

    if (isFirstOpen) {
      firstDrop.style.display = "block";
    } else {
      firstDrop.style.display = "none";
    }

    event.stopPropagation();
  });

  document.addEventListener("click", function(event) {
  if (
    !event.target.closest("#firstBtn") &&
    !event.target.closest("#firstDrop")
  ) {
    const firstDropElement = document.querySelector("#firstDrop");
    if (firstDropElement.style.display !== "none") {
      firstDropElement.style.display = "none";
      isFirstOpen = false;
    }
  }
});

Apa yang saya coba:

– Saya sedang memeriksa apakah ada kesalahan sintaksis, tetapi ternyata tidak ada
– Saya berpikir bahwa saya menggunakan beberapa fungsi lanjutan dan membuat ulang kode saya dengan gelembung tetapi tidak membantu
– Saya berpikir ada masalah dengan acara klik jadi saya menambahkan acara sentuh tetapi tidak membantu
– Saya mencoba menggunakan simulasi di Mac, tetapi kode di dalamnya berfungsi dengan sempurna
– Saya menggunakan simulasi di tumpukan browser dan ada masalah saya
