I have tried with the below code but it's not working as is should.
<?php
$sqlEng = mysql_query('select * from jobs_category');
$count = 1;
while($resEng = mysql_fetch_array($sqlEng)){
if ($count%3 == 1)
{
?>
<div class="col-md-4 padding-left">
<?php } ?>
<ul class="unstyled">
<li><i class="fa fa-angle-right"></i> <?php echo $resEng['name'];?></li>
</ul>
<?php if ($count%3 == 0)
{
?>
</div>
<?php } $count++; } ?>

Answer 1

Assuming you have only 21 records in the table.
try this.
<?php
//$sqlEng = mysql_query('select * from jobs_category');
$servername = "localhost:3306";
$username = "root";
$password = "";
// Create connection
$conn = new mysqli($servername, $username, $password, "stack1");
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
$sqlEng = $conn->query('select * from jobs_category');
$count = 1;
while($resEng = $sqlEng->fetch_assoc()){
if ($count%7 == 1)
{
?>
<div class="col-md-4 padding-left">
<ul class="unstyled">
<?php } ?>
<li><i class="fa fa-angle-right"></i> <?php echo $resEng['name'];?></li>
<?php if ($count%7 == 0)
{
?>
</ul>
</div>
<?php } $count++;
} ?>
tested in my local.

If I get your question correctly, you are trying to spread the list items <li> A Job </li> across three lists <div> <ul> List Items </ul> </div>
<?php
$sqlEng = mysql_query('select * from jobs_category');
$count = 1;
$group_one = "
<div class='col-md-4 padding-left'>
<ul class='unstyled'>
";
$group_two = "
<div class='col-md-4 padding-left'>
<ul class='unstyled'>
";
$group_three = "
<div class='col-md-4 padding-left'>
<ul class='unstyled'>
";
while($resEng = mysql_fetch_array($sqlEng)){
if($count > 3) {
$count = 1;
}
switch ($count) {
case 1:
$group_one .= "
<li><a href='#'><i class='fa fa-angle-right'></i> " .$resEng['name'] . "</a></li>";
break;
case 2:
$group_two .= "
<li><a href='#'><i class='fa fa-angle-right'></i> " .$resEng['name'] . "</a></li>";
break;
case 3:
$group_three .= "
<li><a href='#'><i class='fa fa-angle-right'></i> " .$resEng['name'] . "</a></li>";
}
$count++;
}
$group_one .= "
</ul>
</div>";
$group_two .= "
</ul>
</div>";
$group_three .= "
</ul>
</div>";
echo $group_one . $group_two . $group_three;
?>
