Changing the menu icon is basically an easy thing to do, all you need is an image and a few lines of css. For the icon, we suggest to use an 15 by 15px PNG-image with background-transparency, preferable in plain white to match the style.

The CSS-Selector

To have a better access style-wise, we added a theme-function to automatically add a class, based on the menu-item-title to each menu-link. The class-name consists of the hyphenated title in lowercase with special-characters removed.

For example:

  • the menu-item with the title "Quotes" would have the class-name quotes
  • "My new Menu-item" would have my-new-menu-item
  • and "neuer Menüeintrag" would result in neuer-men-eintrag - note that the "ü" was removed and not replaced.

When in doubt, make sure to check the class-name with the developer tools of your favorite browser.

The Style

Straight to the point:

.pane-menu-erpal-menu a.<menu-item-class-name>:before {
  content: '';
  background: transparent url('<path-to-your-image>/<icon-filename.png>') no-repeat center center;
  height: 30px;
  width: 15px;

Remember to adjust the path and filename of the image, as well as the menu-item-class-name.

Where do I add the new style?

In general there are two options: with a (new custom) module or in a sub-theme.

... in a subtheme

As for the sub-theme, please see the documentation on creating a sub-theme.

... with a new custom module

  1. create a new module-folder

    The folder should be created inside the sites/all/modules-folder. it is considered to be a good practice to collect all custom created modules in a sub-folder named "custom" (so sites/all/modules/custom).

    the name should be all lowercase, without special characters but underscores, e.g. my_awesome_module or custom_erpal_menu_icons. Let's stick with the last one as we go.

  2. create the .info file

    The .info-file is used to store metadata of modules and also to let Drupal know that the module exists. As we just want to add some css it's going to be a very simple one.

    The filename needs to be exactly like the folder-name, in our example

    And this is the basic content:

    name = Custom ERPAL menu-icons
    description = Provides icons for ERPAL-menu-items.
    core = 7.x
    package = ERPAL
    stylesheets[all][] = css/erpal-menu-icons.css

    As you can see we already specified a dependency for a css-file where we can store the new custom styles.

  3. create the .module file

    In our example we don't want to add any additional logic to the module, but still need the .module file, therefore we create a file names custom_erpal_menu_icons.module and add the following lines as we want to stick to a good practice.

     * @file
     * Provide additional styling for the ERPAL menu.
  4. add the styles

    Create a folder called "css" and the style-sheet itself, in our case erpal-menu-icons.css and add the styles to it.

  5. clear cache

    Our best friend - $ drush cc all or by navigating to Configuration » Development » Performance » "Clear all caches"

  6. finally: enable the module

    This can eighter be done by using drush ($ drush en -y <your-modulename> in our case $ drush en -y custom_erpal_menu_icons) or by going to the modules section and enabling it manually.

For additional information on how to create a module and what you can do with it please have a look at creating modules (7.x) on

For advanced users

As we use the great Font Awesome iconset in our ERPAL-theme you have the option to just change the glyph-content, to get an icon of your liking.

So let's say you created a new page listing all your freelance-workers and would like to give it the users-icon. Therefore grab the glyph-code and reformat it so that you can use it for the css content-property and add the respective style (assuming the link title is "Freelancer"):

.pane-menu-erpal-menu a.freelancer:before {
  content: '\xf0c0;';

See the cheat-sheet for information of the glyph-codes.
