+`iron-collapse` creates a collapsible block of content.  By default, the content
+will be collapsed.  Use `opened` or `toggle()` to show/hide the content.
+
+    <button on-click="{{toggle}}">toggle collapse</button>
+
+    <iron-collapse id="collapse">
+      <div>Content goes here...</div>
+    </iron-collapse>
+
+    ...
+
+    toggle: function() {
+      this.$.collapse.toggle();
+    }
+
+`iron-collapse` adjusts the height/width of the collapsible element to show/hide
+the content.  So avoid putting padding/margin/border on the collapsible directly,
+and instead put a div inside and style that.
+
+    <style>
+      .collapse-content {
+        padding: 15px;
+        border: 1px solid #dedede;
+      }
+    </style>
+
+    <iron-collapse>
+      <div class="collapse-content">
+        <div>Content goes here...</div>
+      </div>
