README

A simple Symfony bundle for defining your application's menus in configuration and rendering them to work with Bootstrap's Navbar component. This bundle supports Bootstrap versions 4 and 5.

Installation

$ composer require camurphy/bootstrap-menu-bundle

Usage

Your menus are defined in config/packages/bootstrap_menu.yaml.

Below is a very simple menu called main with only a single 'Logout' link.

bootstrap_menu:
  version: 5 # Optional, defaults to Bootstrap 5
  dropdown_active_style: false # Optional, defaults to false
  dropdown_item_active_style: false # Optional, defaults to false
  menus:
    main:
      items:
        logout:
          label: 'Logout'
          route: 'app_logout'

Then within your template you can render your menu in a Navbar by passing the name of your menu to render_bootstrap_menu. This markup is taken from the Bootstrap Navbar Fixed example. The Bootstrap 4 version is here

<nav class="navbar navbar-expand-md navbar-dark fixed-top bg-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarCollapse" aria-controls="navbarCollapse"
            aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  
    <div class="collapse navbar-collapse" id="navbarCollapse">
      <ul class="navbar-nav me-auto mb-2 mb-md-0">
        {{ render_bootstrap_menu('main') }}
      </ul>
    </div>
  </div>
</nav>

Route parameters

Perhaps your route requires parameters. You can also specify these.

bootstrap_menu:
  menus:
    main:
      items:
        backorder_report:
          label: 'Backorder Report'
          route: 'app_reports'
          route_parameters:
            id: 'backorder'

External URL

If you would instead like to link to an absolute URL, use url instead.

bootstrap_menu:
  menus:
    main:
      items:
        disney:
          label: 'Disney'
          url: 'https://www.disney.com'

Dropdowns

Simply by specifying items instead of a route or url to link to, your menu item becomes a Dropdown. Here's an example where a 'Change Password' and a 'Logout' link are nested below an 'Account' dropdown.

bootstrap_menu:
  menus:
    main:
      items:
        account:
          label: 'Account'
          items:
            change_password:
              label: 'Change password'
              route: 'app_change_password'
            logout:
              label: 'Logout'
              route: 'app_logout'

Result:

Dividers

Dropdowns can also contain Dividers to separate groups of related menu items.

bootstrap_menu:
  menus:
    main:
      items:
        account:
          label: 'Account'
          items:
            change_password:
              label: 'Change password'
              route: 'app_change_password'
            divider:
              is_divider: true
            logout:
              label: 'Logout'
              route: 'app_logout'

Result:

Headers

Dividers that also contain a label become Headers.

bootstrap_menu:
  menus:
    main:
      items:
        account:
          label: 'Account'
          items:
            password_divider:
              is_divider: true
              label: 'Password Stuff'
            change_password:
              label: 'Change password'
              route: 'app_change_password'

            other_divider:
              is_divider: true
              label: 'Other Stuff'
            logout:
              label: 'Logout'
              route: 'app_logout'

Result:

Security

Certain parts of the menu may be locked down by role. This following example only allows administrators to change their password.

bootstrap_menu:
  menus:
    main:
      items:
        account:
          label: 'Account'
          items:
            password_divider:
              is_divider: true
              label: 'Password Stuff'
            change_password:
              label: 'Change password'
              route: 'app_change_password'
              roles: [ 'ROLE_ADMINISTRATOR' ]

            other_divider:
              is_divider: true
              label: 'Other Stuff'
            logout:
              label: 'Logout'
              route: 'app_logout'

For a user without ROLE_ADMINISTRATOR they would see:

The reason for this is Bootstrap Menu Bundle intelligently prunes Dropdowns to remove unnecessary Dividers. Because the user is not permitted to see any items between 'Password Stuff' and 'Other Stuff', the 'Password Stuff' Divider is also pruned.

Security can also be configured at a Dropdown level. Perhaps only administrators are allowed to use the 'Users' menu.

bootstrap_menu:
  menus:
    main:
      items:
        users:
          label: 'Users'
          roles: [ 'ROLE_ADMINISTRATOR' ]
          items:
            user_list:
              label: 'Users'
              route: 'app_user_list'
            new_user:
              label: 'New User'
              route: 'app_new_user'

Negating roles

You may also hide menu items from users that have a certain role by prefixing the role with an exclamation mark. This will take precedence over included roles. In the example below, if they have both ROLE_SUPPORT and ROLE_USER they will not see the menu item.

bootstrap_menu:
  menus:
    main:
      items:
        users:
          label: 'Users'
          roles: [ '!ROLE_SUPPORT', 'ROLE_USER' ]
          items:
            user_list:
              label: 'Users'
              route: 'app_user_list'

Active styles

Out of the box, top level menu items are given the active class when the current route matches the menu item's route. In this example we're on the 'Reports' page.

Dropdown active styles

It's not documented, but the active class also works on dropdowns and dropdown items. To enable for dropdowns, set dropdown_active_style to true in the config.

To enable for dropdown items, set dropdown_item_active_style to true.
