Usage

Implementing Slideout.js into your project is easy.

First of all, you'll need to create your markup. You should have a menu (#menu) and a main content (#panel) into your body.

<nav id="menu">
  <header>
    <h2>Menu</h2>
  </header>
</nav>

<main id="panel">
  <header>
    <h2>Panel</h2>
  </header>
</main>

Add the Slideout.js styles (index.css) in your web application.

body {
  width: 100%;
  height: 100%;
}

.slideout-menu {
  position: fixed;
  top: 0;
  bottom: 0;
  width: 256px;
  min-height: 100vh;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
  z-index: 0;
  display: none;
}

.slideout-menu-left {
  left: 0;
}

.slideout-menu-right {
  right: 0;
}

.slideout-panel {
  position: relative;
  z-index: 1;
  will-change: transform;
  background-color: #FFF; /* A background-color is required */
  min-height: 100vh;
}

.slideout-open,
.slideout-open body,
.slideout-open .slideout-panel {
  overflow: hidden;
}

.slideout-open .slideout-menu {
  display: block;
}

Then you just include Slideout.js, create a new instance with some options and call the toggle method:

<script src="https://github.com/Mango/slideout/raw/master/dist/slideout.min.js"></script>
<script>
  var slideout = new Slideout({
    'panel': document.getElementById('panel'),
    'menu': document.getElementById('menu'),
    'padding': 256,
    'tolerance': 70
  });

  // Toggle button
  document.querySelector('.toggle-button').addEventListener('click', function() {
    slideout.toggle();
  });
</script>

slideout.close();

Slideout.toggle();

slideout.toggle();

Slideout.isOpen();

Returns true if the slideout is currently open, and false if it is closed.

slideout.isOpen(); // true or false

Slideout.destroy();

slideout.destroy();

Slideout.enableTouch();

slideout.enableTouch();

Slideout.disableTouch();

Disables opening the slideout via touch events.

Slideout.off(event, listener);

slideout.off('open', listener);

Slideout.emit(event, ...data);

slideout.emit('open');

Events

An instance of Slideout emits the following events:

The slideout emits translatestart, translate and translateend events only when it is opening/closing via touch events.

slideout.on('translatestart', function() {
  console.log('Start');
});

slideout.on('translate', function(translated) {
  console.log('Translate: ' + translated); // 120 in px
});

slideout.on('translateend', function() {
  console.log('End');
});

// 'Start'
// 'Translate 120'
// 'End'

data-slideout-ignore attribute

<main id="panel">
  <header>
    <h2>Panel</h2>
  </header>
  <div id="carousel" data-slideout-ignore>
    <h2>Carousel</h2>
    ...
  </div>

FAQ

How to add a toggle button.

// vanilla js
document.querySelector('.toggle-button').addEventListener('click', function() {
  slideout.toggle();
});

// jQuery
$('.toggle-button').on('click', function() {
    slideout.toggle();
});

How to open slideout from right side.

You should use the side option with the value right.

var slideout = new Slideout({
  'panel': document.getElementById('content'),
  'menu': document.getElementById('menu'),
  'side': 'right'
});

How to enable slideout only on mobile devices.

You should use mediaqueries:

@media screen and (min-width: 780px) {
  .slideout-panel {
    margin-left: 256px;
  }

  .slideout-menu {
    display: block;
  }

  .btn-hamburger {
    display: none;
  }
}

How to use slideout with a fixed header.

First, you should define the styles for your fixed header:

.fixed-header {
  position: fixed;
  width: 100%;
  height: 50px;
  backface-visibility: hidden;
  z-index: 2;
  background-color: red;
}

Then, using slideout's events you should translate the fixed header:

var fixed = document.querySelector('.fixed-header');

slideout.on('translate', function(translated) {
  fixed.style.transform = 'translateX(' + translated + 'px)';
});

slideout.on('beforeopen', function () {
  fixed.style.transition = 'transform 300ms ease';
  fixed.style.transform = 'translateX(256px)';
});

slideout.on('beforeclose', function () {
  fixed.style.transition = 'transform 300ms ease';
  fixed.style.transform = 'translateX(0px)';
});

slideout.on('open', function () {
  fixed.style.transition = '';
});

slideout.on('close', function () {
  fixed.style.transition = '';
});

How to disable dragging on some elements.

You can use the attribute data-slideout-ignore to disable dragging on some elements:

</main>

How to add an overlay to close the menu on click.

You can do that using the powerful slideout API and a little extra CSS:

.panel:before {
  content: '';
  display: block;
  background-color: rgba(0,0,0,0);
  transition: background-color 0.5s ease-in-out;
}

.panel-open:before {
  position: absolute;
  top: 0;
  bottom: 0;
  width: 100%;
  background-color: rgba(0,0,0,.5);
  z-index: 99;
}
function close(eve) {
  eve.preventDefault();
  slideout.close();
}

slideout
  .on('beforeopen', function() {
    this.panel.classList.add('panel-open');
  })
  .on('open', function() {
    this.panel.addEventListener('click', close);
  })
  .on('beforeclose', function() {
    this.panel.classList.remove('panel-open');
    this.panel.removeEventListener('click', close);
  });
