I just bought the Menu Manager Plugin and if i ad it to the header is coming in just plain text no design

This is the Top Menu code that needs to be added on header file

<?php echo show_menu('1') ?>

This is the Footer Menu that will be added on footer file

<?php echo show_menu('2') ?>
The plugin dose accept custom css so can you please help me out with a custom css button that can be Red like the publish button

@Moderat
I would say you should ask plugin author how to properly configure it

Can you give me a code so i can insert nicely in that position as if i add the code it goes bad and the format of  the header it goes wrong
