Magento2.1 make parent category link not clickable

[jayreis]

I have seen examples of how to do this in 1.x . However I am wondering how I would make a category link that has subcategories under it not clickable. So basically the parent category is not a clickable link? I am not sure of the location of the file to edit also how the code would be modified for 2.1 ? 

I know in Magento 1.x you would do something like the below. However I am still trying to master Magento2.1

// ADD THESE LINES
if (!empty($_hasChildren)) {
     $html .= '<a onclick="return false" style="text-decoration:none; cursor: default;" href="javascript&colon;;" class="'. $outermostClassCode .' '. $_hasChildren .'">'. $this->escapeHtml($this->__($child->getName())) .'</a>';
     } else {
       $html .= '<a href="'. $child->getUrl() .'" class="'. $outermostClassCode .' '. $_hasChildren .'">'. $this->escapeHtml($this->__($child->getName())) .'</a>';
     }

You can remove Top Navigation with main link with below changes,

You just need to override Topmenu.php file from

vendor/magento/module-theme/Block/Html/Topmenu.php

to your custom module.

Replace _getHtml() function with below code,

protected function _getHtml(
        \Magento\Framework\Data\Tree\Node $menuTree,
        $childrenWrapClass,
        $limit,
        $colBrakes = []
    ) {
        $html = '';

        $children = $menuTree->getChildren();
        $parentLevel = $menuTree->getLevel();
        $childLevel = $parentLevel === null ? 0 : $parentLevel + 1;

        $counter = 1;
        $itemPosition = 1;
        $childrenCount = $children->count();

        $parentPositionClass = $menuTree->getPositionClass();
        $itemPositionClassPrefix = $parentPositionClass ? $parentPositionClass . '-' : 'nav-';

        foreach ($children as $child) {
            $child->setLevel($childLevel);
            $child->setIsFirst($counter == 1);
            $child->setIsLast($counter == $childrenCount);
            $child->setPositionClass($itemPositionClassPrefix . $counter);

            $outermostClassCode = '';
            $outermostClass = $menuTree->getOutermostClass();

            if ($childLevel == 0 && $outermostClass) {
                $outermostClassCode = ' class="' . $outermostClass . '" ';
                $child->setClass($outermostClass);
            }

            if (count($colBrakes) && $colBrakes[$counter]['colbrake']) {
                $html .= '</ul></li><li class="column"><ul>';
            }

            $html .= '<li ' . $this->_getRenderedMenuItemAttributes($child) . '>';
            if($child->getLevel() > 0){
            $html .= '<a data-test="'.$child->getLevel().'" href="' . $child->getUrl() . '" ' . $outermostClassCode . '><span>'
                . $this->escapeHtml($child->getName())
                . '</span></a>' . $this->_addSubMenu(
                    $child,
                    $childLevel,
                    $childrenWrapClass,
                    $limit
                ) . '</li>';
            }else{
            $html .= '<a href="javascript&colon;void(0)" ' . $outermostClassCode . '><span>'
                . $this->escapeHtml($child->getName())
                . '</span></a>' . $this->_addSubMenu(
                    $child,
                    $childLevel,
                    $childrenWrapClass,
                    $limit
                ) . '</li>';
            }
            $itemPosition++;
            $counter++;
        }

        if (count($colBrakes) && $limit) {
            $html = '<li class="column"><ul>' . $html . '</ul></li>';
        }

        return $html;
    }

When I replace the gethtml() public function in the vendor/magento/module-theme/Block/Html/Topmenu.php folder with the one you posted above I get a 500 error?
