php and html tag problem when customizing menu items

Question

I was trying to print the menu item description under the menu name.

I add this into the menu.inc under bootstrap theme, where the function bootstrap_menu_link(array $variables) is:

if ($element['#original_link']['menu_name'] == "main-menu" && isset($element['#localized_options']['attributes']['title'])){
    $element['#title'] .="<br> " . $element['#localized_options']['attributes']['title'];
  }

my interface then showed something like product<br>LED Drivers as the menu item - the <br> tag is printed out directly. I looked at the source code, that area shows: <br> , so I then tried using <br> in the php string, but the source code showed <br> this time. How can I correctly insert html tag into $element['#title']?

Answer 1

You could check if where the call to the l() function is created (in the function mentioned: bootstrap_menu_link), the third parameter contains the following element in the array:

'html' => TRUE

This tells drupal to output the title of the link as html and not run it trough check_plain().

Also, I would create a custom theme based on the bootstrap theme and add my customization there.
