Convert a Menu to a Dropdown for Small Screens

The Five Simple Steps website has a responsive design with a neat feature. When the browser window is narrow, the menu in the upper right converts from a regular row of links into a dropdown menu.

When you're on a small screen (iPhone shown here) and click the dropdown, you get an interface to select an option where each option is nice and big and easy to choose.

That sure makes it easier to pick a place to go than a tiny link. Yeah, it's two taps instead of one, but that's arguable since you'd probably have to zoom in to tap the right link otherwise.

The HTML

The HTML for these two menus is different. As far as I know, you can't style <select> and <option> elements to look and behave like <a>s or vice versa. So we need both. You could just put both in the markup. That's what Five Simple Steps does:
<nav> 

  <ul> 
    <li><a href="/" class="active">Home</a></li> 
    <li><a href="/collections/all">Books</a></li> 
    <li><a href="/blogs/five-simple-steps-blog">Blog</a></li> 
    <li><a href="/pages/about-us">About Us</a></li> 
    <li><a href="/pages/support">Support</a></li> 
  </ul> 
  
  <select> 
    <option value="" selected="selected">Select</option> 
    
    <option value="/">Home</option> 
    <option value="/collections/all">Books</option> 
    <option value="/blogs/five-simple-steps-blog">Blog</option> 
    <option value="/pages/about-us">About Us</option> 
    <option value="/pages/support">Support</option> 
  </select> 

</nav>
Let's go with that for now.

The CSS

By default we'll hide the select menu with display: none;. This is actually good for accessibility, as it will hide the redundant menu from screen readers.
nav select {
  display: none;
}
Then using media queries, we'll do the switcheroo at some specific width. You can determine that on your own (here's some standard breakpoints).
@media (max-width: 960px) {
  nav ul     { display: none; }
  nav select { display: inline-block; }
}

But now you gotta maintain two menus?

Well yeah, that's one concern. Maybe your menus are created dynamically and you can't control the output easily. Maybe you and hand crafting menus but want to make sure you don't accidentally get your menus out of sync. One way we can fight this is to dynamically create the dropdown menu from the original.
Using jQuery, we can do that with just a few lines of code:
// Create the dropdown base
$("<select />").appendTo("nav");

// Create default option "Go to..."
$("<option />", {
   "selected": "selected",
   "value"   : "",
   "text"    : "Go to..."
}).appendTo("nav select");

// Populate dropdown with menu items
$("nav a").each(function() {
 var el = $(this);
 $("<option />", {
     "value"   : el.attr("href"),
     "text"    : el.text()
 }).appendTo("nav select");
});
Then to make the dropdown menu actually work...
$("nav select").change(function() {
  window.location = $(this).find("option:selected").val();
});

But aren't dropdown menus kinda obtrusive?

Kinda. Most small screens these days are mobile and most mobile devices are JavaScript friendly, so not a huge concern. But, if you want to ensure this works with or without JavaScript I have an article about that.

WordPress - Custom Content Type Manager




The Custom Content Type Manager requires WordPress 3.3. It allows users to create custom content types (also known as post types) and standardized custom fields for each, including dropdowns, checkboxes, and images. This gives WordPress CMS functionality: Break out of your Blog!

You can select multiple images, posts, or media items to be stored in a single field making it easy for you to store a gallery of images or long lists of values. This plugin also lets you export and import your content definitions, making it easy to ensure a similar structure between multiple sites.

Check the site for a full list of features.

This plugin was written in part for the book WordPress 3 Plugin Development Essentials, published by Packt.
