PHP - Can't Dynamically Create Images

Hi,

I have a table row that has a dropdown and two textboxes in it.

I would like to use a button that allows me to add another row beneath the existing row.  It cannot be added to the bottom of the table as there is further content beneath.

The content of the dropdown comes from a database query.

The dropdown on the new row should have the selection in the first row greyed out.

I expect this will need to be a js function but i dont really know where to start with it being dynamic content.

This is the table as it stands if this provides clarity of my intentions - picture below

					echo "<form method='post' id='staffOrderForm'>";
							$stmt->close();
										echo "<table id='staffOrderTable' class='table table-striped table-bordered mt-3 text-center'>";
						foreach($daterange as $date){
														
									echo"
										<tr>
											<th class='table-dark' colspan='3'>".$date->format("l - jS F Y")."</th>
										</tr>
										<tr>
											<th class='' colspan='3'>Management	</th>
										</tr>
										<tr>
											<th class='col-4'>Name</th>
											<th class='col-4'>Start Time</th>
											<th class='col-4'>End Time</th>
										</tr>
										<tr>
											<td>
												<select class='custom-select managerSelect'>";
												$managerRoleId = 1;
												$stmt = $conn->prepare("
												 	SELECT user_firstname, user_lastname, user_id
												    FROM ssm_user
												    WHERE user_role_id = ? ");
												$stmt->bind_param("i", $managerRoleId);
												$stmt->execute();
												$stmt->store_result();
												$stmt->bind_result($ufn, $uln, $uid);
												while($stmt->fetch()){echo "<option>".$ufn." ".$uln."</option>";};
												echo"</select>
											</td>
											<td><input class='form-control' type='' name=''></td>
											<td><input class='form-control' type='' name=''></td>
										</tr>
										<tr>
											<th colspan='3'>Chefs</th>
										<tr/>
										<tr>
											<th class='col-4'>Name</th>
											<th class='col-4'>Start Time</th>
											<th class='col-4'>End Time</th>
										</tr>
										<tr>
											<td>
												<select class='custom-select chefSelect'>";
													$chefRoleId = 2;
													$stmt = $conn->prepare("
												 	SELECT user_firstname, user_lastname, user_id
												    FROM ssm_user
												    WHERE user_role_id = ? ");
													$stmt->bind_param("i", $chefRoleId);
													$stmt->execute();
													$stmt->store_result();
													$stmt->bind_result($ufn, $uln, $uid);
													while($stmt->fetch()){echo "<option>".$ufn." ".$uln."</option>";};
												echo"</select>
											</td>
											<td><input class='form-control' type='' name=''></td>
											<td><input class='form-control' type='' name=''></td>
										</tr>";
						}
						echo "</table></form>";

I appreciate that i will likely have to add a button with an onclick but from there i am pretty lost.

As always i appreciate the help provided.

<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>

<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>

<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
	if(!empty($_POST['fSelected']))
	{
		$chosen = $_POST['fSelected'];
		foreach ($chosen as $item)
			echo "aID selected: $item </br>";
		$delimit = implode(", ", $chosen);
		print_r($delimit);
	}

}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
	$aTitle[] = $row[ 'name' ];
}
}
?>

<table>
	
		<?php if(isset($delimit)) { 
		$c=0; foreach($aTitle as $item) {?>
		<tr>
		<td>
			<?php echo $aTitle[$c]; $c++;?>
		</td>
		</tr>
		<?php }}?>
