How do I make a drop down menu?

Question

 <ul id="MenuBar2" class="MenuBarHorizontal"> <li><a class="MenuBarItemSubmenu" href="#">Item 1</a> <ul> <li><a href="#">Mr</a></li> <li><a href="#">Mrs</a></li> <li><a href="#">Miss</a></li> <li><a href="#">Ms</a></li> <li><a href="#">Master</a></li> <li><a href="#">Prof.</a></li> <li><a href="#">Dr</a></li> </ul> </li> </ul> 

This is the code that I have used on Dreamweaver Cs6. The drop down works however, when I click on one of the titles, it doesn't select it. Could someone explain how to fix this problem please.

Thanks :)

Answer 1

If you are using the default Spry menu provided by Dreamweaver, you have to make sure that in the head section that SpryMenuBar.js and SpryMenuBarHorizontal.css are included.

If so you have also to insert

<script type="text/javascript">
 var MenuBar2 = new Spry.Widget.MenuBar("MenuBar2", {imgDown:"SpryAssets/SpryMenuBarDownHover.gif", imgRight:"SpryAssets/SpryMenuBarRightHover.gif"});
</script>

before </body>

So you end code should look like this

 (function() { // BeginSpryComponent if (typeof Spry == "undefined") window.Spry = {}; if (!Spry.Widget) Spry.Widget = {}; Spry.BrowserSniff = function() { var b = navigator.appName.toString(); var up = navigator.platform.toString(); var ua = navigator.userAgent.toString(); this.mozilla = this.ie = this.opera = this.safari = false; var re_opera = /Opera.([0-9\\.]*)/i; var re_msie = /MSIE.([0-9\\.]*)/i; var re_gecko = /gecko/i; var re_safari = /(applewebkit|safari)\\/([\\d\\.]*)/i; var r = false; if ( (r = ua.match(re_opera))) { this.opera = true; this.version = parseFloat(r[1]); } else if ( (r = ua.match(re_msie))) { this.ie = true; this.version = parseFloat(r[1]); } else if ( (r = ua.match(re_safari))) { this.safari = true; this.version = parseFloat(r[2]); } else if (ua.match(re_gecko)) { var re_gecko_version = /rv:\\s*([0-9\\.]+)/i; r = ua.match(re_gecko_version); this.mozilla = true; this.version = parseFloat(r[1]); } this.windows = this.mac = this.linux = false; this.Platform = ua.match(/windows/i) ?

You can include Bootstrap to your website and follow these examples:

• Dropdowns
• Beautiful Dropdowns
• Split button Dropdowns
