The Menu State

The {{burger-menu}} component exposes multiple contextual components, but it also exposes a state object.

You can use the menu state object to modify pretty much any property.

• open
• width
• position
• animation
• itemAnimation
• customAnimation

The state object also exposes some actions:

• open

  <button {{action burger.state.actions.open}}>Open</button>

• close

  <button {{action burger.state.actions.close}}>Close</button>

• toggle

  <button {{action burger.state.actions.toggle}}>Toggle</button>

Custom Animations

If you're not impressed with the in-house animations and want to create your own, all you have to do is pass the following class to the customAnimation property in the {{burger-menu}} component. If you think your animation would be a good addition to the existing collection, feel free to open a PR with it!

import Animation from 'ember-burger-menu/animations/base';

export default Animation.extend({
  // CSS class names to be able to target our menu
  animation: 'my-custom-animation',
  itemAnimation: 'my-custom-item-animation',

  container(open, width, right) {
    return {};
  },

  outlet(open, width, right) {
    return {
      transform: open ? right ? `translate3d(-${width}px, 0, 0)` : `translate3d(${width}px, 0, 0)` : ''
    };
  },

  menu(open, width, right) {
    return {};
  },

  menuItem(open, width, right, index) {
    return {
      transform: open ? '' : `translate3d(0, ${(index + 1) * 500}px, 0)`
    };
  }
});

Note: You don't need to worry about prefixing your CSS attributes as it will be done for you.

If you need to add some base CSS to your animation, you can target the menu as such:

.ember-burger-menu.bm--my-custom-animation {
  #{$bm-menu} {}
  > .bm-outlet {}

  &.is-open {
    #{$bm-menu} {}
    > .bm-outlet {}
  }
}

And the menu items as such:

.ember-burger-menu.bm-item--my-custom-item-animation {
  #{$bm-menu} {
    .bm-menu-item {}
  }

  &.is-open {
    #{$bm-menu} {
      .bm-menu-item {}
    }
  }
}

To use our new custom animation, all we have to do is pass the class to the customAnimation option in the {{burger-menu}} component.

import MyCustomAnimation from 'path/to/my-custom-animation';

export default Ember.Component.extend({
  MyCustomAnimation
});

{{#burger-menu customAnimation=MyCustomAnimation}}
  ...
{{/burger-menu}}
