Menu display at top

It's an issue with the padding assigned in Fusion Core's style.css file. You'll want to look at line 385 in the aforementioned file and copy the code you see there. It'll look like this:

/* style links, and unlinked parent items (via Special Menu Items module) */
.primary-menu ul li a,
.primary-menu ul li .nolink {
  display: block;
  padding: 0.75em 1em;
  text-decoration: none;
}

Copy that chuck and paste it in to Celadon's local.css file (if you don't have one, you can create one), but alter the padding as shown below:

/* style links, and unlinked parent items (via Special Menu Items module) */
.primary-menu ul li a,
.primary-menu ul li .nolink {
  display: block;
  padding: 0em 1em;
  text-decoration: none;
}

That should fix it.

Thanks for solving that out, I ran into same problem.

But problems with Celadon do not stop there. When Superfish menu is enabled, it has just short items as it is noted in #721202: Drop Down Menu to Short.

I tried putting width: auto on various places, however, I have never achieved what it is supposed to do, to have equal widths for all submenu items.

Can you please look at this and solve?

This theme looks good, it is shame that developer is not looking into these bugs and not resolving.

It is questionable if theme is abandoned completely :(

UPDATE: I've done little harder and came up with solution in #721202: Drop Down Menu to Short. Just add this code to your local.css

#primary-menu.block ul {
margin-left: 0;
width: auto;
}

#1 does the job. Should be coded into local.css by default.

#1 saved my day ;)

This answer works the best for me http://drupal.org/node/721202#comment-3079896

Great responses in here guys, thanks, this helped out a lot. I had the same issues as above.

Thanks so much for solving this! I love the theme...but this was driving me crazy.
