Magento 1.9 – How to Disable Category URL from Menu

This may not be exactly what you need, and it will not work if you have a lot of attributes but it might help you.
I recommend you this free extension. It allows you to build custom product lists and add links to them in the main menu based on some rules. The rules are managed in the same way as you manage the catalog discount rules.
A full description on what it does and how can be found here.

So you have to create a rule for each attribute and each value of that attribute.
You might need to work a bit on it to group the menu items somehow.
Like I said, if you have a lot of attributes and a lot of values for them it may not work for you.

You can modified in category view file as per your custom requirement

copy file

app/design/frontend/base/default/template/catalog/category/view.phtml

to your theme

app/design/frontend/your_package/your_theme/template/catalog/category/view.phtml

and change code something like

<?php
    $_helper    = $this->helper('catalog/output');
    $_category  = $this->getCurrentCategory();
    $_imgHtml   = '';
    if ($_imgUrl = $_category->getImageUrl()) {
        $_imgHtml = '<p class="category-image"><img src="'.$_imgUrl.'" alt="'.$this->htmlEscape($_category->getName()).'" title="'.$this->htmlEscape($_category->getName()).'" /></p>';
        $_imgHtml = $_helper->categoryAttribute($_category, $_imgHtml, 'image');
    }
?>
<div class="page-title category-title">
    <?php if($this->IsRssCatalogEnable() && $this->IsTopCategory()): ?>
        <a href="<?php echo $this->getRssLink() ?>" class="link-rss"><?php echo $this->__('Subscribe to RSS Feed') ?></a>
    <?php endif; ?>
    <h1><?php echo $_helper->categoryAttribute($_category, $_category->getName(), 'name') ?></h1>
</div>

<?php echo $this->getMessagesBlock()->getGroupedHtml() ?>

<?php if($_imgUrl): ?>
    <?php echo $_imgHtml ?>
<?php endif; ?>

<?php if($_description=$this->getCurrentCategory()->getDescription()): ?>
    <div class="category-description std">
        <?php echo $_helper->categoryAttribute($_category, $_description, 'description') ?>
    </div>
    <?php endif; ?>

<?php $manufacturer = Mage::app()->getRequest()->getParam('manufacturer'); ?>

<?php if($this->isContentMode() && !$manufacturer): ?>
    <?php echo $this->getCmsBlockHtml() ?>

<?php elseif($this->isMixedMode()): ?>
    <?php echo $this->getCmsBlockHtml() ?>
    <?php echo $this->getProductListHtml() ?>

<?php else: ?>
    <?php echo $this->getProductListHtml() ?>
<?php endif; ?>

Also make sure you don't have mix mode for any other category or you need to put condition for that also.
