默认情况下，在下拉列表中选择第一个选项

Question

默认情况下，在下拉列表中选择第一个选项。我想取消选择它。以下是我的代码

<label>Select from below</label>
<div>
  <select name="subjects[]" class="ms"  id="subjects" class="form-control ">
    <option value=''>SELECT</option>
    <?php  foreach ($subjects as $s) {
      echo '<option value=' . $s->sb_id . '>' . $s->subject_name . '</option>';
    } ?>
  </select>

现在这里也正在选择“SELECT”
