The example above imported slide which renders a menu that slides in on the page when the burger icon is clicked. To use a different animation you can subsitute slide with any of the following

• Slide
• ScaleDown
• ScaleRotate
• Reveal
• Push
• PushRotate

ATTENTION - the below animations are in WIP

• FallDown
• Stack
• Elastic
• Bubble

Properties

Some animation require certain other elements on your page

• Page wrapper - an element wrapping the rest of the content on yur page, placed after the menu component

<Menu/>

<main id="page-wrap">
.
.
</main>

• Outer container called app - an element containing everything including the menu component

<div id="app">
    <Menu/>
    <main id="page-wrap">
    .
    .
    .
    </main>
</div>

Check this table to see which animations require these elements:

Animation	pageWrapId	appId
Slide
Push	✓	✓
PushRotate	✓	✓
ScaleDown	✓	✓
ScaleRotate	✓	✓
Reveal	✓	✓

Position

The menu opens from left by default. To have it open from the right, use the right prop. It's just a boolean so you don't need to specify a value.

<Slide right/>

Width

You can specify the width of the menu with the width prop. The default is 300px

<Slide width="400">

Open state

You can control whether the sidebar is open or closed with the isOpen prop. This is useful if you need to close the menu after a user clicks on an item in it, for example, or if you want to open the menu from some other button in addition to the standard burger icon. The default value is false

// To render the menu open

<Slide isOpen>

Menu events

If you want to get a notification when the menu open or close you can use the openMenu and closeMenu notifications. This way you can update your application state when the menu open or close

// To bind the open and close events

<Slide
  @openMenu="handleOpenMenu"
  @closeMenu="handleCloseMenu"
>

Close on Outside Click

You can turn off the menu closing when an an outside click is triggered with disableOutsideClick.

<Slide disableOutsideClick>

Close on Escape

By default, the menu will close when the Escape key is pressed. To disable this behavior, you can pass the disableCloseOnEsc prop. This is useful in cases where you want the menu to be open all the time, for example if you're implementing a responsive menu that behaves differently depending on the browser width.

<Slide disableEsc />

Close on Navigation

By default, the menu will not close when a link inside the menu is clicked. To disable this behavior, you can pass the closeOnNavigation prop. This is useful in cases where you want the menu to close when a navigation link is clicked as this then stops the user having to make an extra click to close the menu.

<Slide :closeOnNavigation="true" />

Overlay

You can turn off the default overlay with noOverlay.

<Slide noOverlay />

Burger Icon and Cross Icon

You can disable both icons by passing burgerIcon and crossIcon to false. This can be useful if you want to keep the menu open and don't want the user to close the menu

<Slide :burgerIcon="false" :crossIcon="false"/>

Styling

Visual styles (color, font etc) need to be supplied with the help of CSS

CSS

 .bm-burger-button {
      position: fixed;
      width: 36px;
      height: 30px;
      left: 36px;
      top: 36px;
      cursor: pointer;
    }
    .bm-burger-bars {
      background-color: #373a47;
    }
    .line-style {
      position: absolute;
      height: 20%;
      left: 0;
      right: 0;
    }
    .cross-style {
      position: absolute;
      top: 12px;
      right: 2px;
      cursor: pointer;
    }
    .bm-cross {

    }
    .bm-cross-button {
      height: 24px;
      width: 24px;
    }
    .bm-menu {
      height: 100%; /* 100% Full-height */
      width: 0; /* 0 width - change this with JavaScript */
      position: fixed; /* Stay in place */
      z-index: 1000; /* Stay on top */
      top: 0;
      left: 0;
      background-color: rgb(63, 63, 65); /* Black*/
      overflow-x: hidden; /* Disable horizontal scroll */
      padding-top: 60px; /* Place content 60px from the top */
      transition: 0.5s; /*0.5 second transition effect to slide in the sidenav*/
    }

    .bm-overlay {
      background: rgba(0, 0, 0, 0.3);
    }
    .bm-item-list {
      color: #b8b7ad;
      margin-left: 10%;
      font-size: 20px;
    }
    .bm-item-list > * {
      display: flex;
      text-decoration: none;
      padding: 0.7em;
    }
    .bm-item-list > * > span {
      margin-left: 10px;
      font-weight: 700;
      color: white;
    }
