答
Here is your answer, it will select your last select dropdown state...
Remove id from option <option id="emp" use class if you want, or use unique id.
<select name="attendance-list" id="attendance-list" class="form-control" >
<?php
$save_drop_down_value = $this->input->post('attendance-list"');
//change this line according to your project..
foreach($attendance_dropdown as $value) {
$select = "";
if( $save_drop_down_value == $value['emp_id']){
$select = "selected";
}
?>
<option <?php echo $select; ?> value="<?php echo $value['emp_id'];?>">
<?php echo $value['emp_name'];?>
</option>
<?php } ?>
