Yes, thats what happens. But if you keep the right float as it is now, this is what you can do to get the right order:

- open up index.template.php and find:
// Show the menu up top. Something like [home] [help] [profile] [logout]...
function template_menu()
{
global $context, $settings, $options, $scripturl, $txt;

if(empty($settings['nomootools']))
echo '
<div id="menu_container">
<ul id="nav">';
else
echo '
<div id="main_menu">
<ul class="dropmenu" id="menu_nav">';

the add this right after that:
// reverse the order
$newbuttons = array_reverse($context['menu_buttons'], true);
$context['menu_buttons'] = $newbuttons;


That should make them reversed, so floating right should be correct. Let me know if it works.

If its not related to Impulse, start a new. Otherwise its fine.

The drop-down menus..as in the part that "drops" lol?

That is a actually a setting for that Mootools based menu. You need to open index.template.php again and find this code:

if(empty($settings['nomootools']))
echo '<!-- Load the MenuMatic Class -->
<script src="'.$settings['theme_url'].'/js/MenuMatic_0.68.3.js" type="text/javascript" charset="utf-8"></script>

<!-- Create a MenuMatic Instance -->
<script type="text/javascript" >
window.addEvent(\'domready\', function() {
var myMenu = new MenuMatic({
duration:\'250\'
});
});
if(document.getElementById(\'admnav\'))
{
window.addEvent(\'domready\', function() {
var myMenu = new MenuMatic({
id:\'admnav\',
subMenusContainerId:\'admsubMenus\',
duration:\'250\'
});
});
}
  </script>';
then exchange it with:

if(empty($settings['nomootools']))
echo '<!-- Load the MenuMatic Class -->
<script src="'.$settings['theme_url'].'/js/MenuMatic_0.68.3.js" type="text/javascript" charset="utf-8"></script>

<!-- Create a MenuMatic Instance -->
<script type="text/javascript" >
window.addEvent(\'domready\', function() {
var myMenu = new MenuMatic({
duration:\'250\',
opacity:\'80\'
});
});
if(document.getElementById(\'admnav\'))
{
window.addEvent(\'domready\', function() {
var myMenu = new MenuMatic({
id:\'admnav\',
subMenusContainerId:\'admsubMenus\',
opacity:\'80\',
duration:\'250\'
});
});
}
  </script>';

The "opacity" value is what counts, 100 means no opacity. As you can see you can also set the "duration" for the dropmenu, set it lower(100 for example, used on this site) and it goes faster. Higher means slower.

Also note the second set of values is for admin menus only. Note also that this will ONLY work using the Mootools menu option, not the normal SMF menu.
