Use BBCode

The wijeditor widgets supports BBCode, or Bulletin Board Code, which is a markup language used to format posts in message boards. Simply set the mode option in the script to take advantage of this feature. See the Editor > BBCode sample of the MVC Control Explorer live demo at http://demo.componentone.com/ASPNET/MVCExplorer/editor/BBCode .

<script id="scriptInit" type="text/javascript">
            $(document).ready(function () {
                  $("#wijeditor").wijeditor({ mode: "bbcode", editorMode: "split" });
            });
</script>

Create an ASP.NET MVC 5 Wijmo application.
In the Solution Explorer, expand the View | Shared folder and double-click _Layout.cshtml to open the file.

Add the following markup within the <body> tags of the page.

<body>
<div class="demo">
        <textarea id="wijeditor" style="width: 756px; height: 475px;">
                <h1>heading</h1>
                <p>Your Content Here</p>
        </textarea>
        </div>

After the closing </div> tag you added in the previous step, enter the following jQuery script to initialize the wijeditor widget:

<script id="scriptInit" type="text/javascript">
            $(document).ready(function () { $("#wijeditor").wijeditor({ mode: "bbcode", editorMode: "split" }); });
                   </script>

Press F5 to run the application.
