MyBB Community Forums

On my forum, I have a navbar. Here is the code at the moment:

<table class="tnav" border="0" cellspacing="0" cellpadding="0" align="center">
<tr align="center">
<td class="navbar"><a href="{$mybb->settings['bburl']}/member.php?action=register">{$lang->welcome_register}</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/portal.php">Home</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/index.php">Forums</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/memberlist.php">{$lang->toplinks_memberlist}</a></td><td class="navbar"><a href="search.php?action=getnew">{$lang->welcome_newposts}</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/search.php?action=getdaily">{$lang->welcome_todaysposts}</a></td>
<td class="navbar"><a href="$settings[bburl]/search.php">{$lang->toplinks_search}</a></td>
</tr>
</table>

I would like to add a drop-down list when I mouse over "Home" with Help, Links, and anything else.

You can try the solution here:

Or find one here and customize your self:

You'll of course need to upload any java script files to your server and direct it there.

You can use the built in JavaScript although that won't be on hover, that would require a click:

<table class="tnav" border="0" cellspacing="0" cellpadding="0" align="center">
<tr align="center">
<td class="navbar"><a href="{$mybb->settings['bburl']}/member.php?action=register">{$lang->welcome_register}</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/portal.php" id="home_menu">Home</a>
<div id="home_menu_popup" class="popup_menu" style="display: none;">
	<div class="popup_item_container"><a href="misc.php?action=help" class="popup_item">Help</a></div>
	<div class="popup_item_container"><a href="#" class="popup_item">Links</a></div>
	<div class="popup_item_container"><a href="#" class="popup_item">Other</a></div>
	<div class="popup_item_container"><a href="#" class="popup_item">Other</a></div>
	<div class="popup_item_container"><a href="#" class="popup_item">Other</a></div>
</div>
<script type="text/javascript">
// <!--
	if(use_xmlhttprequest == "1")
	{
		new PopupMenu("home_menu");
	}
// -->
</script>
</td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/index.php">Forums</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/memberlist.php">{$lang->toplinks_memberlist}</a></td><td class="navbar"><a href="search.php?action=getnew">{$lang->welcome_newposts}</a></td>
<td class="navbar"><a href="{$mybb->settings['bburl']}/search.php?action=getdaily">{$lang->welcome_todaysposts}</a></td>
<td class="navbar"><a href="$settings[bburl]/search.php">{$lang->toplinks_search}</a></td>
</tr>
</table>

Otherwise the best method is to use CSS, Google for "CSS dropdown menu".
