How to make website menu dropdown on hover rather than click

Looking for some help. I'm helping to upgrade a website from Drupal 7 to 8. One of the problems I cannot resolve is how to make the drop-down menus display when you hover over them.

You can see how it works on the live site here: https://eerr.org.uk/

And how it does not work here: https://www.drupal8.eerr.org.uk/

I wonder if someone can help me out, I am not good with CSS and HTML so any advice welcome.

Thanks Mark

EDIT

I am really hoping someone can help me edit the existing code not just send me a link to creating dropdown menus in stand-alone code.

The existing code seems to be generated in the following .twig file (Again I have no experience in developing in this)

themes/contrib/bootstrap_barrio/templates/navigation/menu--main.html.twig

'''

{#
/**
 * @file
 * Bootstrap Barrio's override to display a menu.
 *
 * Available variables:
 * - menu_name: The machine name of the menu.
 * - items: A nested list of menu items. Each menu item contains:
 *   - attributes: HTML attributes for the menu item.
 *   - below: The menu item child items.
 *   - title: The menu link title.
 *   - url: The menu link url, instance of \Drupal\Core\Url
 *   - localized_options: Menu link localized options.
 *   - is_expanded: TRUE if the link has visible children within the current
 *     menu tree.
 *   - is_collapsed: TRUE if the link has children within the current menu tree
 *     that are not currently visible.
 *   - in_active_trail: TRUE if the link is in the active trail.
 */
#}
{% import _self as menus %}

{#
  We call a macro which calls itself to render the full tree.
  @see http://twig.sensiolabs.org/doc/tags/macro.html
#}
{{ menus.menu_links(items, attributes, 0) }}

{% macro menu_links(items, attributes, menu_level) %}
  {% import _self as menus %}
  {% if items %}
    {% if menu_level == 0 %}
      <ul{{ attributes.addClass('nav navbar-nav') }}>
    {% else %}
      <ul class="dropdown-menu">
    {% endif %}
    {% for item in items %}
      {%
        set classes = [
          menu_level ? 'dropdown-item' : 'nav-item',
          item.is_expanded ? 'menu-item--expanded',
          item.is_collapsed ? 'menu-item--collapsed',
          item.in_active_trail ? 'active',
          item.below ? 'dropdown',
        ]
      %}
      <li{{ item.attributes.addClass(classes) }}>
        {%
          set link_classes = [
            not menu_level ? 'nav-link',
            item.in_active_trail ? 'active',
            item.below ? 'dropdown-toggle',
            item.url.getOption('attributes').class ? item.url.getOption('attributes').class | join(' '),
            'nav-link-' ~ item.url.toString() | clean_class,
          ]
        %}
        {% if item.below %}
          {{ link(item.title, item.url, {'class': link_classes, 'data-toggle': 'dropdown', 'aria-expanded': 'false', 'aria-haspopup': 'true' }) }}
          {{ menus.menu_links(item.below, attributes, menu_level + 1) }}
        {% else %}
          {{ link(item.title, item.url, {'class': link_classes}) }}
        {% endif %}
      </li>
    {% endfor %}
    </ul>
  {% endif %}
{% endmacro %}

Keep in mind that hover is not mobile friendly.

This is just an advice ; there's no hover event on mobiles and touch pads. So if your website might be used on these devices, you should either keep click or implement the touch event.

}
<div class="dropdown">
  <button class="dropbtn">Dropdown</button>
  <div class="dropdown-content">
