+title: IFrame Plugin
+---
+
+The iframe plugin provides the functionality to open sidebar & navbar items in a tabbed iframe.
+
+##### Required Markup
+To get the iframe 100% working you need the following content-wrapper markup:
+
+```html
+<div class="content-wrapper iframe-mode" data-widget="iframe" data-loading-screen="750">
+  <div class="nav navbar navbar-expand-lg navbar-white navbar-light border-bottom p-0">
+    <a class="nav-link bg-danger" href="#" data-widget="iframe-close">Close</a>
+    <ul class="navbar-nav" role="tablist"></ul>
+  </div>
+  <div class="tab-content">
+    <div class="tab-empty">
+      <h2 class="display-4">No tab selected!</h2>
+    </div>
+    <div class="tab-loading">
+      <div>
+        <h2 class="display-4">Tab is loading <i class="fa fa-sync fa-spin"></i></h2>
+      </div>
+    </div>
+  </div>
+</div>
+```
+
+##### Usage
+This plugin can be activated as a jQuery plugin or using the data api. 
+
+###### Data API
+{: .text-bold }
+Activate the plugin by adding `data-widget="iframe"` to the `.content-wrapper`. If you need to provide onCheck and onUncheck methods, please use the jQuery API. 
+
+###### jQuery
+{: .text-bold }
+The jQuery API provides more customizable options that allows the developer to handle checking and unchecking the todo list checkbox events. 
+```js
+$('.content-wrapper').IFrame({
+  onTabClick(item) {
+    return item
+  },
+  onTabChanged(item) {
+    return item
+  },
+  onTabCreated(item) {
+    return item
+  },
+  autoIframeMode: true,
+  autoItemActive: true,
+  autoShowNewTab: true,
