Interaction

Drawer content here

Web Component
HTML Blueprint

Modify the active attribute or property to make the drawer show or hide. The chi-drawer element also has three public methods to interact with it: show(), hide(), toggle().

<chi-button id="drawer-trigger" type="icon">
  <chi-icon icon="menu"></chi-icon>
</chi-button>

<chi-drawer id="interactive-drawer" position="right" backdrop>
  <div class="-px--2 -text">Drawer content here</div>
</div>

<script>
  var drawer = document.getElementById('interactive-drawer');
  var drawerTrigger = document.getElementById('drawer-trigger');
  drawerTrigger.addEventListener('click', function(){
    drawer.toggle();
    // or drawer.active = !drawer.active;
  });
</script>

This HTML Blueprint requires JavaScript. You may use your own solution, or use Chi's vanilla JavaScript solution, Chi.js.

Use the function chi.drawer(elem) to instantiate a new drawer component in the DOM element passed as a parameter. You must use the trigger element as the parameter.

<button id="drawer-trigger-1" class="chi-button -icon chi-drawer__trigger" data-target="#drawer-1" aria-label="Toggle navigation">
  <div class="chi-button__content">
    <i class="chi-icon -sm--2 icon-menu"></i>
  </div>
</button>

<div class="chi-backdrop -closed">
  <div class="chi-backdrop__wrapper">
    <div id="drawer-1" class="chi-drawer -right">
      <div class="chi-drawer__header">
        <button class="chi-button -icon -close" aria-label="Close">
          <div class="chi-button__content">
            <i class="chi-icon icon-x"></i>
          </div>
        </button>
      </div>
      <div class="chi-drawer__content">
        <div class="-px--2 -text">Drawer content here</div>
      </div>
    </div>
  </div>
</div>

<script>chi.drawer(document.getElementById('drawer-trigger-1'));</script>

Preventing memory leaks

Drawer components have a dispose function to free all resources attached to the element, such as event listeners and object data. You should call this method when you want to remove the component.

var elem = document.getElementById('drawer-1');
var drawer = chi.drawer(elem);
// do stuff
drawer.dispose();

It is safe to call the drawer method more than once, as it will return any previously created drawer component associated to the trigger.

var elem = document.getElementById('drawer-2');
var drawer = chi.drawer(elem);
var elem2 = document.getElementById('drawer-2');
var drawer2 = chi.drawer(elem2);
drawer === drawer2; // returns true

drawer.dispose(); // Only have to do it once.
