Anything is possible in the magical world of software, not only can it be done but there are many different ways of achieving it.

Here is a rough example:
<https://jsfiddle.net/n6fm39ww/>

HTML

```
<select name="start_time">
</select>

<select name="end_time">
  <option value="default">Pick a start time</option>
</select>

```

JS

```
// Add each option to start_times
for (var hour = 9; hour <= 21; hour++) {
  var option = "<option value='"+hour+"'>"+hour+"</option>";
    $('[name="start_time"]').append(option);
}

// When the start time is changed, set the end time
$('[name="start_time"]').on('change', function() {
    // This is the start time chosen
  var start_time = $(this).val();
  // Remove the default option
  $('[name="end_time"]').find('option').remove();
  // Add options after the start time
  for (var hour = parseInt(start_time) + 1; hour <= 24; hour++) {
      var option = "<option value='"+hour+"'>"+hour+"</option>";
    $('[name="end_time"]').append(option);
  }
});

```
Please make sure to provide code samples in the future.

Here is an example of how that is done: <https://jsfiddle.net/c6432wee/>

---

Say we have two selects.

`<select id="startTime">
 <option value="na">Please Select A Time</option>
 <option value=1>1:00PM</option>
</select>`

`<select id="endTime">
 <option value="na">Please Select A Time</option>
 <option value=1>1:00PM</option>
</select>`

We start by setting the end time hidden

`$('#endTime').css('display', 'none');`

Then we register an event handler. Everytime it is changed, we look at the value to see if it different from our default placeholder.

```
  $('#startTime').change(function () {
    if($('#startTime').val() !== 'na') {
      $('#endTime').css('display', 'initial');
    }
  });

```

If it is, we set endTime back to its initial display state.

`$('#endTime').css('display', 'initial');`
