okay, here you go (no styling other than for the menu):
http://cookasite.com/15j/modx/index.php?id=631) i created a new template, called it "newTemplate" ( just copy and pasted the minimal template and deleted its own css reference and wayfinder call )
2) placed your wayfinder call in the template:
[[Wayfinder? &startId=`0` &level=`3` &parentClass=`hide` &parentRowTpl=`cssplay_parentRow` &outerTpl=`cssplay_outer` &innerTpl=`cssplay_inner` &rowTpl=`cssplay_row` &outerClass=`menu` &cssTpl=`cssplay_dropdown`]]
3) copied the dropdown css code in the header ( a quick fix because i can't upload the css files on your server -> your files should be here:
http://cookasite.com/15j/modx/assets/templates/wayfinder/dropdown.css ):
/* common styling */
.menu {font-family: arial, sans-serif; width:750px; position:relative; margin:0; font-size:11px; margin:2px 0 100px 0; z-index:100;}
.menu ul li a, .menu ul li a:visited {display:block; text-decoration:none; color:#000;width:104px; height:20px; text-align:center; color:#fff; border:1px solid #fff; background:#710069; line-height:20px; font-size:11px; overflow:hidden;}
.menu ul {padding:0; margin:0;list-style-type: none; }
.menu ul li {float:left; margin-right:1px; position:relative;}
.menu ul li ul {display: none;}
/* specific to non IE browsers */
.menu ul li:hover a {color:#fff; background:#36f;}
.menu ul li:hover ul {display:block; position:absolute; top:21px; left:0; width:105px;}
.menu ul li:hover ul li a.hide {background:#6a3; color:#fff;}
.menu ul li:hover ul li:hover a.hide {background:#6fc; color:#000;}
.menu ul li:hover ul li ul {display: none;}
.menu ul li:hover ul li a {display:block; background:#ddd; color:#000;}
.menu ul li:hover ul li a:hover {background:#6fc; color:#000;}
.menu ul li:hover ul li:hover ul {display:block; position:absolute; left:105px; top:0;}
.menu ul li:hover ul li:hover ul.left {left:-105px;}
for IE:
.menu ul li a.hide, .menu ul li a:visited.hide {display:none;}
.menu ul li a:hover ul li a.hide {display:none;}
.menu ul li a:hover {color:#fff; background:#36f;}
.menu ul li a:hover ul {display:block; position:absolute; top:21px; left:0; width:105px;}
.menu ul li a:hover ul li a.sub {background:#6a3; color:#fff;}
.menu ul li a:hover ul li a {display:block; background:#ddd; color:#000;}
.menu ul li a:hover ul li a ul {visibility:hidden;}
.menu ul li a:hover ul li a:hover {background:#6fc; color:#000;}
.menu ul li a:hover ul li a:hover ul {visibility:visible; position:absolute; left:105px; top:0; color:#000;}
.menu ul li a:hover ul li a:hover ul.left {left:-105px;}
but they should actually be placed as css files in assets/templates/wayfinder/dropdown.css & assets/templates/wayfinder/dropdown_ie.css
4) created a new ressource "MenuTest" and assigned the template "newTemplate" to it
hope i could help to understand the issue
