I have a web page with a dropdown menu that when selected the information is shown on the page. However, the list is growing as I add more content. What I now need is three dropdown menus, for example, header, sub header, and sub sub header. Then have the selected data shown on one page.
I am able to copy and paste the same dropdown menu, but this is not what I need. I have tried three tables and changing the variables to match the tables but this means adding the <?php ?> code twice e.g. <?php echo header ?><?php echo sub header ?> which displays both sets of data.
How do I have three dropdown menus, using data from three tables displayed on one page?

Navigation code:
<div class="container" id="contents"> <div class="row"> <div class="col-md-4 box"> <div>dropdown box 1</div> </div><!-- col end: --> <div class="col-md-4 box"> <div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Select Option </button> <div class="dropdown-menu text-center" aria-labelledby="dropdownMenuButton"> <?php $q = "SELECT * FROM pages"; $r = mysqli_query($dbc, $q); while($nav = mysqli_fetch_assoc($r)) { echo '<a class="dropdown-item box" href="?page='.$nav['id'].'">'.$nav['title'].'</a>'; } ?> </div><!-- dropdown menu end: --> </div><!-- dropdown end: --> </div><!-- col end: --> <div class="col-md-4 box"> <div>Dropdown box 3</div> </div><!-- col end: --> </div><!-- row end: --> </div><!-- contents container end: -->

The set up code:
function links
include(‘functions/data.php’); // for page set up
# page setup if(isset($_GET['page'])) { $pageid = $_GET['page']; // set $pageid to equal the value to the url } else { $pageid = 1; // set $pageid equal to 1 or the home page } $page = data_page($dbc, $pageid); // see data.php: $pageid = $id # page set up end
-
The function code:
<?php # function to display all pages from database function data_page($dbc, $id) { $q = "SELECT * FROM pages WHERE id = $id"; // id was $Pageid $r = mysqli_query($dbc, $q); $data = mysqli_fetch_assoc($r); return $data; } # function end ?>

The body code:
<div class="col-md-2"> <h4><strong><?php echo $page['slug']; ?></strong></h4> </div><!-- col end: --> <div class="col-md-4"> <h4 class="text-justify"><?php echo $page['body']; ?></h4> </div><!-- col middle end: --> <div class="col-md-3"> <h4>Facts</h4> <h5 class="text-justify"><?php echo $page['facts']; ?></h5> </div><!-- col end: --> <div class="col-md-3" id="sidebar"> <h5 class="text-justify"><?php echo $page['sidebar']; ?></h5> </div><!-- col right end: --> </div><!-- row end: -->
I am new to php so need any advice to be ‘an idiots’ guide type.
Thanks in advance for any help.
