If there are over 500 records, why are options not displayed in the datalist?

function loadAllDynamicOptions() {
  let dataList = document.getElementById("browsers");
  let options = '';
  for (let i = 0; i < 1200; i++) {
    options += '<option value="datalist' + i + '">datalist' + i + '</option>';
  }
  dataList.innerHTML = options;
}
loadAllDynamicOptions();
<form action="/action_page.php" method="get">
  <label for="browser">Choose your browser from the list:</label>
  <input list="browsers" name="browser" id="browser">
  <datalist id="browsers">

        </datalist>
  <input type="submit">
</form>

<p><strong>Note:</strong> The datalist tag is not supported in Safari 12.0 (or earlier).</p>

May I suggest a solution on how to display all values in the datalist? Instead of loading limited options, you can display all 1200 dynamic options by calling the "loadAllDynamicOptions()" function. This function has a loop that dynamically generates all the necessary options with the required values and assigns them to the datalist. Below is the example code to use:

Thank you for sharing your code snippet. The function "loadAllDynamicOptions()" generates all the necessary options with the required values and assigns them to the datalist. This way, you can display all 1200 dynamic options. You can call this function to display all options instead of loading limited options. Here is an example code that you can use: 
function loadAllDynamicOptions() {
  let dataList = document.getElementById("browsers");
  let options = '';
  for (let i = 0; i < 1200; i++) {
    options += '<option value="datalist' + i + '">datalist' + i + '</option>';
  }
  dataList.innerHTML = options;
}
loadAllDynamicOptions();
I hope this helps! Let me know if you have any other questions.

The datalist element only displays a certain number of options by default. To display all 1200 options, you can set the size attribute of the datalist element to be equal to the number of options you have, like so: 
<datalist id="browsers" size="1200">
This will display all 1200 options in the datalist. However, keep in mind that this may cause performance issues in some browsers, as it would cause the page to render a very large number of elements. It's usually recommended to limit the number of options in a datalist to a reasonable amount for a better user experience.
