Lightword theme question

do you mean the horizontal pages menu on the top?

maybe by removing this code section from header.php:

<ul id="front_menu"<?php echo lw_expmenu(); ?>>
<?php echo lw_homebtn(__('Home','lightword')); ?>
<?php echo lw_wp_list_pages();  ?>
</ul>

(however, i am not sure if this is from the latest version of lightword)

this might also be possible using css.

link to your site?
