Navigation bar issue

I am running into the issue where I can't add any more pages in the griddy theme because it will not resize the font of the text on the navigation bar. Instead it pushes the plugin links 'contribute an item" to the next line out of the style context.

Essentially, leaving it as it is I have a gap at the end of the navigation bar that looks bad.

Below is an image of what I am referring to. Next to the contribute an item the | line bugs me!

I'm not familiar with the griddy theme, but you should be able to modify the font size of your navigation bar in the screen.css file in your theme's css folder. In my theme I'd add something like this to the #primary-nav li styling

#primary-nav li {font-size:10px;

Another thing you might consider is changing the wording of your tabs, so they take up less space. I think the default tabs read something like "Browse Items | Browse Collections" and you could change it to "Items | Collections". Less space, but still a readable font size.

In the common folder of your theme, there's a file called header.php. You'll want to replace some of the following code:

<?php echo public_nav_main(array('Home' => uri(''), 'Browse Items' => uri('items'), 'Browse Collections'=>uri('collections'))); ?>

Just remove "Browse", and you've got smaller tabs.

You can do similar modifications to the plugin tabs. Just find where the navigation function is located, like in the Contribute plugin's ContributionPlugin.php file:

public function publicNavigationMain($nav)
    {
        $nav['Contribute an Item'] = contribution_contribute_url();
        return $nav;
    }

And change it from 'Contribute an Item' to 'Add an Item'.

I was trying this before, however the space still remains, just larger than it is now. The space remains, but the sizing is different. It is never gone completely. It makes it look as though something was supposed to be there and isn't if I change the font or the names of the links.

This should all be CSS work.

Add the following to the screen.css to get rid of the right border on the last navigation item.

#primary-nav li:last-child {
    border-right: 0;
    }

If you want to center all the navigation items to even out that extra space, replace this chunk of css...

#primary-nav {
	height: 40px;
	font-size: 14px;
	font-weight: bold;
	margin-bottom: 20px;
	text-transform: uppercase;
	}

	#primary-nav a:link, #primary-nav a:visited {color: #666;}
	#primary-nav a:hover {color: #333;}

	#primary-nav li {
		height: 20px;
		border-right: 1px solid #999;
		float: left;
		list-style-type: none;
		margin: 0;
		padding: 10px 20px;
		}

... with this chunk of css.

#primary-nav {
	height: 40px;
	font-size: 14px;
	font-weight: bold;
	margin-bottom: 20px;
	text-transform: uppercase;
	text-align: center;
	}

	#primary-nav a:link, #primary-nav a:visited {color: #666;}
	#primary-nav a:hover {color: #333;}

	#primary-nav li {
		height: 20px;
		border-right: 1px solid #999;
		display:inline-block;
		list-style-type: none;
		margin: 0;
		padding: 10px 20px;
		}

That works for it's current configuration. But I still am unable to add anymore pages or links in my navigation bar. The image below shows this example.

Admittedly, the griddy theme was built with only a few navigation items in mind. My recommendations echo Andy's: shorter nav labels and maybe bumping down the font-size if that's not enough.

Okay I will give that a shot. Where do I find the "browse exhibits" label? It is not in the header.php file. I checked the exhibit builder plugin directory and can't seem to locate it in any of those files either.

Thanks!!

The codex has a good page that details how to change the navigation labels. http://omeka.org/codex/Editing_the_Main_Navigation

Cancel the last, I won't need it. I was able to add the link that I needed without having to rename the labels. Thanks!! Great help!

For future reference, the Browse Exhibits nav header text is located in the plugin's functions.php file: /plugins/ExhibitBuilder/functions.php

I've tried to shorten "Browse Collections" to "Collections" and "Browse Items" to "Items" but anytime I attempt to alter the header.php file in any way my site stops working. I'm following these directions (http://omeka.org/codex/Editing_the_Main_Navigation) exactly. What's the problem?

@wilkel11, can you post your markup?
