I'm using the Understrap theme for Wordpress and looking to modify the default menu on mobile when the user clicks the hamburger menu.
Essentially I am trying to get the menu to fully overlay the screen. Hoping someone can help. I thought there might be a bootstrap4 class to achieve this.
<?php
/**
* The header for our theme.
*
* Displays all of the <head> section and everything up till <div id="content">
*
* @package understrap
*/
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly.
}
$container = get_theme_mod( 'understrap_container_type' );
?>
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="profile" href="http://gmpg.org/xfn/11">
<?php wp_head(); ?>
</head>
<body <?php body_class(); ?>>
<div class="site" id="page">
<!-- Main Header Above Nav -->
<section class="main-header container-fluid">
<header class="container">
<div class="col-lg-6 col-md-6 col-sm-12 col-xs-12">
<!-- Your site title as branding in the menu -->
<?php if ( ! has_custom_logo() ) { ?>
<?php if ( is_front_page() && is_home() ) : ?>
<h1 class="navbar-brand mb-0"><a rel="home" href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" itemprop="url">
<?php bloginfo( 'name' ); ?></a></h1>
<?php else : ?>
<a class="navbar-brand" rel="home" href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" itemprop="url">
<?php bloginfo( 'name' ); ?></a>
<?php endif; ?>
<?php } else {
the_custom_logo();
} ?><!-- end custom logo -->
</div>
<div class="col-lg-3 col-md-3 hidden-sm-down">

</button>
<!-- The WordPress Menu goes here -->
<?php wp_nav_menu(
array(
'theme_location' => 'primary',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'navbarNavDropdown',
'menu_class' => 'navbar-nav ml-auto',
'fallback_cb' => '',
'menu_id' => 'main-menu',
'depth' => 2,
'walker' => new Understrap_WP_Bootstrap_Navwalker(),
)
); ?>
<?php if ( 'container' == $container ) : ?>
</div><!-- .container -->
<?php endif; ?>
</nav><!-- .site-navigation -->
