SmartMenus jQuery Website Menu - Bootstrap 4 Addon - Navbar fixed bottom

# SmartMenus Bootstrap 4 Addon (Navbar fixed bottom)

Zero config advanced Bootstrap navbars with SmartMenus jQuery and the SmartMenus jQuery Bootstrap 4 Addon.

You just need to include the JS/CSS files on your Bootstrap 4 powered pages and everything should work automatically including full support for your Bootstrap 4 theme. And you also have the power and flexibility of SmartMenus jQuery at hand should you need to tweak or customize anything.

## Source Code

### CSS

In addition to Bootstrap's CSS just include the SmartMenus jQuery Bootstrap 4 Addon CSS. It's just static CSS code you don't need to edit at all (and probably shouldn't try to).

    <!-- Bootstrap core CSS -->
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">

    <!-- SmartMenus jQuery Bootstrap 4 Addon CSS -->
    <link href="../addons/bootstrap-4/jquery.smartmenus.bootstrap-4.css" rel="stylesheet">

### HTML

Note: Bootstrap 4 normally uses `<div>` elements as `.dropdown-menu` containers. But since we are building a multi-level menu tree, we need to replace them with nested `<ul>`/`<li>` elements.

    <nav class="navbar navbar-expand-lg navbar-dark bg-dark mb-4">

    </nav>

### JavaScript

In addition to Bootstrap's JavaScript just include SmartMenus jQuery and the SmartMenus jQuery Bootstrap 4 Addon. The default options used in `jquery.smartmenus.bootstrap.js` should work well for all. However, you can, of course, tweak them if you like.

    <!-- jQuery first, then Popper.js, then Bootstrap JS -->
    <script src="http://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js" integrity="sha384-h0AbiXch4ZDo7tp9hKZ4TsHbi047NrKGLO3SEJAg45jXxnGIfYzk4Si90RDIqNm1" crossorigin="anonymous"></script>

    <!-- SmartMenus jQuery plugin -->
    <script type="text/javascript" src="../jquery.smartmenus.js"></script>

    <!-- SmartMenus jQuery Bootstrap 4 Addon -->
    <script type="text/javascript" src="../addons/bootstrap-4/jquery.smartmenus.bootstrap-4.js"></script>

## Quick customization

### `data-*` attributes

The Bootstrap 4 addon introduces the following additional `data-*` attributes which can be set to any `.navbar-nav`:

- `data-sm-skip` - this will tell the script to skip this navbar and not apply any SmartMenus features to it so it will behave like a regular Bootstrap navbar.
- `data-sm-skip-collapsible-behavior` - this will tell the script to not apply SmartMenus' specific behavior to this navbar in collapsible mode (mobile view). Bootstrap's behavior for navbars in collapsible mode is to use the whole area of the parent items just as a toggle button for their sub menus and thus it's impossible to set a link to the parent items that can be followed on click/tap. SmartMenus' behavior is to add a separate +/- sub menus toggle button to parent items and thus allows the link of the parent items to be activated on the second click/tap (the first click/tap displays the sub menu if it's not visible). If you need even further control, you can check the `collapsibleBehavior` SmartMenus option which can be set in a `data-sm-options` attribute.

### Options

The following additional option can be set in a `data-sm-options` attribute:

- `bootstrapHighlightClasses: 'text-dark bg-light'` - CSS class(es) for highlighting expanded parent dropdown items.

Check the docs for a complete list of all the available SmartMenus options.

### API

The following methods are available:

- `jQuery.SmartMenus.Bootstrap.init()` - reinit the addon. Useful if you add any navbars dynamically on your page and need to init them at any time (all navbars are normally initialized ondomready).
