# MainNavVertical

Used for styles of vertically orientated main application menus/navigation.

Menu item active state is applied on `.is-active` `<li>` elements. Additionally you can use the following placeholders for setting certin states manually:

- `%menu-nav-vertical-action-active` The 'active' or currently selected state.
- `%menu-nav-vertical-action-intent` The highlighted state, usually for `:hover`
  and `:focus`.

`%menu-nav-vertical-hoisted` will 'hoist' an `<li>` element to the top of the
containing block, the containing block defaults to the current viewport. If
you need to define a different ancestor for a containing block you can use
`transform` (see below).

```hbs preview-template
<div class="wrapper">
  <nav class="main-nav-vertical in-viewport">
    <ul>
      <li role="separator">Title</li>
      <li>
        <a href="">One</a>
      </li>
      <li class="is-active">
        <a href="">Two (is-active)</a>
      </li>
      <li class="with-intent">
        <a href="">Three (with-intent)</a>
      </li>
      <li class="hoisted">
        <a href="">Four (hoisted)</a>
      </li>
      <li role="separator">Title</li>
      <li class="custom-active">
        <a href="">One (custom-active)</a>
      </li>
      <li>
        <a href="">Two</a>
      </li>
      <li>
        <a href="">Three</a>
      </li>
    </ul>
  </nav>
</div>
```

```css preview-template
.main-nav-vertical {
  @extend %main-nav-vertical;
}
.main-nav-vertical li.hoisted {
  @extend %main-nav-vertical-hoisted;
}
.main-nav-vertical .with-intent > * {
  @extend %main-nav-vertical-action-intent;
}
.main-nav-vertical .custom-active > * {
  @extend %main-nav-vertical-action-active;
}
.wrapper {
  /* a transform is required to mark this element as the containing block */
  /* for hoisting, otherwise the viewport is the containing block */
  transform: translate(0, 0);
  background-color: var(--gray-600);
  padding-top: 64px;
}
