dropdown with no submit

So I’ve a dropdown menu that has an inventory of all pages utilizing a sure template, when the consumer selects a dropdown merchandise id like them to be re-directed to that web page.

Here’s what I’ve up to now…

            <div class="col-md-6 col-md-offset-3">
                <?php
                //create a var utilizing get_pages create an array and get all web page names
                $pages =  get_pages(array(
                    'meta_key' => '_wp_page_template',
                    'meta_value' => 'template-services.php'
                ));
                ?>
                <p>Searching for one thing else?</p>
                <choose id="cat" class="form-control">
                    <?php
                    // for every merchandise in pages array assign to the brand new var web page
                        foreach( $pages as $web page ) {
                        //echo out var web page for every merchandise within the array
                            echo '<possibility>' . $page->post_title . '</possibility>';
                        }?>
                </choose>
            </div>

Might somebody present me how I can obtain this? I do know there’s a script on the WordPress codex that means that you can do that for classes however I do not know the best way to modify it to work for my wants
