Theming a custom menu block in Drupal 7 So I created a custom menu through the Drupal administration and named it "More Menu." Its machine name, menu-more-menu, was auto-generated by Drupal.

Creating this menu automatically created its corresponding block, and its now available under Blocks administration as More Menu. I then enabled the block and placed it under my desired Region.

I wanted to theme the output of this block. I tried creating a template by following the template suggestion as described here, block--module--delta.tpl.php.

The template file I created was named block--menu--menu-more-menu.tpl.php.

It doesn't seem to work, and I still cannot override it.

Am I missing something?
For custom menu blocks the format for the block template file name is 

block--menu--&lt;menu_machine_name&gt;.tpl.php 


Note: All machine names begin with the 'menu_' prefix and all hyphens are converted to underscores.
