Video: Using Superfish for accessible menus

Now that we've carefully styled our menu, it looks exactly the way we want, and it also works really well as long as we're using a mouse. The problem is if you try to navigate this menu using other means, let's say a keyboard. You'll see that although I can navigate the main menu, when I get to the menu items that have drop down items like about the test or level one. I can't access the drop down items and this is a very common problem you'll run into all over the web all of the time. Menus are great as long as you're using a mouse, but they're not very accessible.

Using Superfish for accessible menus

Now that we've carefully styled our menu, it looks exactly the way we want, and it also works really well as long as we're using a mouse. The problem is if you try to navigate this menu using other means, let's say a keyboard. You'll see that although I can navigate the main menu, when I get to the menu items that have drop down items like about the test or level one. I can't access the drop down items and this is a very common problem you'll run into all over the web all of the time. Menus are great as long as you're using a mouse, but they're not very accessible.

So we need to make our menus accessible because we don't know how people are going to access this theme. They may use a mouse, but they may also use a keyboard or a text-to speech browser or something else. Or they may just have trouble using their mouse. because for example, if you try to navigate to the sub-menu here. And you're not careful you might drop the menu before you get to it. So it's actually really annoying to work with if you don't have a very adequate mouse or if you have reduced motor skills. A lot of work has been done on making menus responsive and the best solution I've been able to find is one called Super Fish.

Now Superfish is a extended version of a JavaScript library called Suckerfish, which creates drop down menus using jQuery. And Superfish adds additional accessibility tools on top of Suckerfish. Which is why it's a Superfish. Superfish is published under the MIT license and is free to use. So, you can simply go to this website and then download it. So go to download and then download the zip archive. And I've already downloaded it to my computer and extracted it on my desktop.

So here I have the folder. That comes from Superfish. It's called Superfish Master. And inside you have lots of files. So the only file we actually need here is under the dist folder and under js and it's called superfish.men.js. Now I'm going to take this file and copy it into my theme. So here I have my WordPress install on the right. Then I'm going to go to WP content > Themes > my simone > JS. And here, I'm going to copy superfishmn.js and paste it into my theme, so that it becomes available to the theme.

Next, I need to make my theme load up the Superfish JavaScript. And any time you're loading up a JavaScript, you should always en-queue the JavaScript. And we're going to do that from functions.php. So here I'll scroll down to the en queue section. And you'll remember, this is where we on queued our customs fonts previously, and those were styles. But now we're going to en queue a script instead. And we already have a couple of scripts en queue, so we can see what they look like. Here we have the function call, wp enqueue_script. It's followed by name for the script.

Then, the location of the script, then you can provide an array of dependencies and you'll see in a second what that means. And then, you can provide a version number and whether or not you want the script to load in the header or the footer. If the last value is set to false, it'll load in the header. If it's set to true, it'll load in the footer. And in most cases you want JavaScript to load in the footer. Now we're going to enqueue Superfish. So if you go to the code snippets and you copy out the first code snippet here. This is the script that will enqueue Superfish.

So here I'll place it directly above my samone navigation. Because this is also related to navigation. And here you'll see that I set the handle for this enqueue function to my_simone_superfish. I am calling the JS folder and superfish.min.js. This script depends on JQuery. So I've set JQuery as a dependency and I'm going to set the version number to today's date. So that's 2014/04/04. And finally, I'm loading the script in the footer. Now I can save functions on PHP.

And go back to my browser and I have to make sure that the script is loading properly now, so that my on Q function works. So, reload the page and then I will click anywhere and inspect element to open the developer tools. And here I will go to Resources> Frames > Local Hosts. Scripts and see if superfish min .js appears. And it does which means we now have it enqueueed into our site. But now super fish just sits there and does nothing. We need to actively tell it what to do.

So to do that, we need to create a new JavaScript. That explains true Superfish exactly what we want it to do. The way Superfish works is, we tell it which unordered list is the menu. And then, it applies a bunch of JavaScript and styles within that unordered list. So first we need to find the name of our menu. So right click on any of the menu elements here. And look at my menu here and then you see that the outermost unordered list has the class nav-menu.

So that's the class that we want to target. Now I need to go back to WordPress, and here I have to create a new file. So I'll go to the JS folder. And here, I'll create a new file by right-clicking on the folder. So selecting New, and I want to create a Java script file. So I'm going to call this file superfish settings. And this file is now going to contain the superfish settings. I've already prepared the settings for you, so. You can go back to the code snippets and here you have the superfish-settings.js script.

And I'll copy it and paste it in and then I'll explain to you exactly how this works. In this file we start off by saying this is the jQuery function. We set a variable called SF, which is a super fish variable. And we say that that variable is matching the UL, so the unordered list, with the class nav menu. So that, you'll remember, is the unordered list that wraps the entire menu. Then we say, on this item, so on the variable SF, run superfish. And you set the delay to 200 and the speed to fast.

I'll show you what that means in one second. So I'm going to save this file, now we have the settings for Superfish. But of course, they live in a separate file here. So we need to en queue that file as well. So I'll go back to functions.php, and I'll go back to my code snippets, and copy out the second function here. And paste it in directly below my simone superfish. And here I'll show you something really neat. So here I'm enqueuing a new script called my simone superfish settings. It works the same way, here we have a template directory, and we're calling js superfish settings.

But then in my dependencies I've made this script dependent on the previous one we created. My simone superfish so that I know that when the first one loads the second one will load too. Now I can save functions.php. Notice all I did was create that JavaScript file, target the ul with a class. And we will now go back to our menu and reload the page. You'll see two things. First of all, when I hover over a menu item, you notice there's a short delay in how the menu item is loaded.

And if I go out of it, it takes a little while before it collapses. So this addresses that issue I was talking about where you accidentally leave the menu. And this is that value that was saying delay. And also how fast it operates. So here you can go back to your settings and if you want the delay to be longer you just increase the number here. And if you want the speed of the fade in and out to be slower, you can just change it from fast to slow. But more importantly, if I now use my keyboard to navigate through my menu. You'll see when we get to a drop down menu, the drop down opens.

And now we can go through each of the menu items. And, when we get to a drop down menu with a submenu, then we can go through those items. So now, we have a fully accessible menu all thanks to Superfish.
