Notice: if you are using a Prestashop version newer than 1.6.0.11, it’s recommended to apply this modification with an override, as explained here: How to override Prestashop modules

Open up modules/blocktopmenu/blocktopmenu.php

Locate the following method:

protected function generateCategoriesMenu($categories, $is_children = 0)

Inside it, you will notice a conditional block

			if (isset($category['children']) && !empty($category['children']))
			{
				$html .= '<ul>';
				$html .= $this->generateCategoriesMenu($category['children'], 1);

				if ((int)$category['level_depth'] > 1 && !$is_children)
				{
					$files = scandir(_PS_CAT_IMG_DIR_);

					if (count($files) > 0)
					{
						$html .= '<li class="category-thumbnail">';

						foreach ($files as $file)
							if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1)
								$html .= '<div><img src="'.$this->context->link->getMediaLink(_THEME_CAT_DIR_.$file)
								.'" alt="'.Tools::SafeOutput($category['name']).'" title="'
								.Tools::SafeOutput($category['name']).'" class="imgm" /></div>';

						$html .= '</li>';
					}
				}

				$html .= '</ul>';
			}

We can do a number of things here. If we comment it out, all submenus will be removed. Otherwise, we can reduce and limit the subcategory levels:

			if ($category['level_depth'] < 4 && isset($category['children']) && !empty($category['children']))
			{
			...

In this case, levels over 3 will not be displayed!

Text version

If you just uploaded to a Prestashop version higher 1.5.6, you will have noticed you can’t move categories anymore from the back office. Actually, this is only half true, you can move categories… if you do what Prestashop wants.

By default, to make the shy arrows pop out, you have to sort by position ascendant, by clicking the button highlighted in the next picture. Boring, huh? If you hit rese,t they will vanish again.

To take them back by default, we therefore need to tell Prestashop to sort by position (ascendant) if no sorting parameter is passed. Open up AdminCategoriesController, that you can find in controllers/admin. You can use an override if you prefer, I will go ahead and edit the core file. Locate”

	public function getList($id_lang, $order_by = null, $order_way = null, $start = 0, $limit = null, $id_lang_shop = false)
	{
		parent::getList($id_lang, $order_by, $order_way, $start, $limit, Context::getContext()->shop->id);
		// Check each row to see if there are combinations and get the correct action in consequence

		$nb_items = count($this->_list);
		for ($i = 0; $i < $nb_items; $i++)
		{
			$item = &$this->_list[$i];
			$category_tree = Category::getChildren((int)$item['id_category'], $this->context->language->id);
			if (!count($category_tree))
				$this->addRowActionSkipList('view', array($item['id_category']));
		}
	}

At the very beginning, add:

	public function getList($id_lang, $order_by = null, $order_way = null, $start = 0, $limit = null, $id_lang_shop = false)
	{
		if(!Tools::getValue('categoryOrderby'))
			$order_by = 'position';
		if(!Tools::getValue('categoryOrderway'))
			$order_way = 'asc';
	}

Explanation: we are simply telling Prestashop to use order by position adcendant if no category order parameter is passed (aka: we didn’t click anything or tried to input any filter).

The final method:

	public function getList($id_lang, $order_by = null, $order_way = null, $start = 0, $limit = null, $id_lang_shop = false)
	{

		if(!Tools::getValue('categoryOrderby'))
			$order_by = 'position';
		if(!Tools::getValue('categoryOrderway'))
			$order_way = 'asc';

		parent::getList($id_lang, $order_by, $order_way, $start, $limit, Context::getContext()->shop->id);
		// Check each row to see if there are combinations and get the correct action in consequence

		$nb_items = count($this->_list);
		for ($i = 0; $i < $nb_items; $i++)
		{
			$item = &$this->_list[$i];
			$category_tree = Category::getChildren((int)$item['id_category'], $this->context->language->id);
			if (!count($category_tree))
				$this->addRowActionSkipList('view', array($item['id_category']));
		}
	}

Refresh the back office, reset all filters, and you will have the arrows back

Adding the visual editor to category description the proper way

Open up your Prestashop root folder, then navigate to controllers/admin and open AdminCategorisController.php in your favorite code editor.

Locate the renderForm method, at about line 321 (Prestashop 1.5.4.0). Inside it, locate the following snippet

				array(
					'type' => 'textarea',
					'label' => $this->l('Description:'),
					'name' => 'description',
					'lang' => true,
					'rows' => 10,
					'cols' => 100,
					'hint' => $this->l('Invalid characters:').' <>;=#{}',
				),

Change so it looks like this:

				array(
					'type' => 'textarea',
					'label' => $this->l('Description:'),
					'name' => 'description',
					'lang' => true,
					'rows' => 10,
					'cols' => 100,
					'hint' => $this->l('Invalid characters:').' <>;=#{}',
					'autoload_rte' => true
				),

As you can see we have added ‘autoload_rte’ => true. This enables the visual editor. Save and access a category page in the back office to see the visual editor.

However, this way your changes will inevitably be overrridden at the next prestashop update you do. We need to use an override.

Using an override for the controller

Back to your prestashop root, go to override/controllers/admin and create a file called AdminCategorisController.php. Paste the following snippet inside

Change so it looks like this:

<?php

Class AdminCategoriesController extends AdminCategoriesControllerCore
{

?>

Note: We are extending a prestashop class (controller in this case). If you want to know more about this, head over here.

In the original AdminCategoriesController, copy the whole renderForm function we just modified, and paste it inside our new override.

Okay, at this point you might notice that the method is calling parent::renderForm(); at the end, right before the closing bracket. Therefore, change the following line

return parent::renderForm();

to

return AdminController::renderForm();

Tip: if we didn’t do this, the original one would have overridden this one no matter what, and no changes would have taken place

Lastly, head over to the root folder again then cache/ and delete the class_index.php file, so that our changes take place. At this point, you can also restore the original adminCategoriesController to its defaults, since we are extending it in a maintainable way.

Here is the complete override (you can download it as a project file)

…And! if you would like more freedom with the visual editor, or simply the possibility to add html / javascript / css content everywhere in Prestashop/s front office, have a look at my module HTML Block!
