For those using Simple Template System (STS) ver 4+, to replace the STS categories box with Dynamic Menu System in your STS template:

Open /includes/modules/sts_inc/sts_column_left.php

Find:
// Get categories box from db or cache
if ((USE_CACHE == 'true') && empty($SID)) {
echo tep_cache_categories_box();
} else {
include(DIR_WS_BOXES . 'categories.php');
}

Change to:
// Get categories box from db or cache
if ((USE_CACHE == 'true') && empty($SID)) {
echo tep_cache_categories_box();
} else {
include(DIR_WS_BOXES . 'dm_categories.php');
}

Open /path to your/sts_template.html

Place $categorybox into your STS template page wherever you want the new dynamenu box to appear.

Follow dynamenu instructions for style of menu you want to appear.

I recommend copying and pasting the dynamenu css into your catalog stylesheet.css - makes it easier on STS templates to link to.
