I was looking at some requirements from a client for their new SharePoint 2013 Intranet, and one that caught my eye was desire to have Feature images on the top navigation.<\/p>\n

The requirement was to have a dynamic top navigation, controlled using the SharePoint out of the box navigation settings, but have the ability to add a Feature image and some text to the menu. My first reaction was to think about a custom navigation control in the master page using Tokens in the navigation settings, then I got to thinking, could we do this with JQuery instead?<\/p>\n

Here\u2019s a brief mock-up of what they wanted to achieve.<\/p>\n

\"image\"<\/a><\/p>\n

So this weekend I decided to take the matter offline and have a play in my SP2013 development environment and this is what I came up with. If nothing else, it’s a great example of what you can do with some well placed tokens and a little jQuery code!<\/p>\n

The first thing I did was take a look at the options available to us in the out of the box navigation, Not much has changed to the navigation interface in recent versions of SharePoint apart from the addition of Managed Metadata base navigation now in 2013. For this example, I’m just using the standard Navigation that forms part of the basic site structure, however there’s no real reason why you couldn’t use the same token based system in the Managed metadata.<\/p>\n

\"clip_image001\"<\/a><\/p>\n

In the actual navigation pane, I’ve added some standard links, and then finally a tokenised link that I’ll be using the jQuery to replace.<\/p>\n

\"clip_image002\"<\/a><\/p>\n

The real key with what I wanted to achieve is to make it easy for the client to be able to change the data that exists in these Big menus. So if we edit one of the tokenised options, you can see that we’re just using the default out of the box navigation fully.<\/p>\n

We place the token in the title field, using the format ~### to denote the start of the token, then a unique identifier for this particular navigation node, and then the closing token identifier ###~. Then the url of the Image that we want to display in the URL field, and then finally the HTML that we want to display in the description field which can include full HTML.<\/p>\n

(Note: Audiencing will still work on these menu’s too!)<\/p>\n

\"clip_image003\"<\/a><\/p>\n

When we save this back into the navigation, and then display our page, this is the effect we get when we hover over that particular top level node.<\/p>\n

\"clip_image004\"<\/a><\/p>\n

So, how did we actually achieve this? The secret is in the jQuery scripts embedded into the master page (In this demo, I’m just using a content editor web part linked to an external html file to make it easy to test and demonstrate!)<\/p>\n

I won\u2019t describe the CSS here as it should hopefully be fairly self explanatory and I\u2019ve commented the jQuery code fairly well. I would say that you can and should condense any JavaScript code that you place into your production environment however for demonstration purposes, this code is spaced out and more verbose than I would write for production.. (tldr THIS IS NOT PRODUCTION CODE!)<\/p>\n

\n
\r\n
\r\n\/\/First we need to find all of our DOM elements that are in the Top level navigation\r\n\/\/and contain the start of the token field.\r\n$("UL.dynamic span.menu-item-text:contains('~###')").each(function(){\r\n\r\n\/\/We then extract the token identifier, removing the ~### and ###~ from either side\r\nvar menuItem = $(this);\r\nvar parentMenuA = menuItem.closest("a");\r\nvar parentMenuUL = menuItem.closest('UL.dynamic');\r\nvar menuToken = menuItem.text().replace('~###','').replace('###~','');\r\n\r\n\/\/Then we extract the link to the image, and to the description field (Held in the title attribute)\r\nvar imageUrlHREF = parentMenuA.attr("href");\r\nvar linkUrlText = parentMenuA.attr("title");\r\n\r\n\/\/Then we hide the tokenised menu item as the user doesn't need to see it.\r\nmenuItem.hide();\r\n\r\n\/\/Now we add an extra class to the Parent UL to apply some CSS\r\nparentMenuUL.addClass('featuredNavigation');\r\n\r\n\/\/And then wrap the original contents of the menu in an extra div to make styling them into the top right hand corner easier\r\nparentMenuUL.wrapInner("<div class='navItemsWrapper'\/>").wrapInner("<div class='navWrapper' id='" + menuToken +  "'><\/div>");\r\n\r\n\/\/Finally we build the Featured image with the data from the navigation item\r\nvar imageDiv = "<div class='navWrapperImageDiv'><img class='navWrapperImage' src='" + imageUrlHREF + "' alt='Featured Image'><\/img>" +\r\n\t"<div class='navWrapperImageText'>" + linkUrlText + "<\/div><\/div>";\r\n\r\n\/\/And then inject it into the top of the navigation object using the prepend instruction.\r\n$('#' + menuToken).prepend(imageDiv);\r\n});\r\n<\/pre>\n<\/div>\n
That\u2019s all the javascript there, though you can download the entire html file that I created for testing and embed it into a SharePoint page using a CEWP to see it in action in your environment.<\/p>\n

I hope it sparked some ideas.<\/p>\n
