Category tree

tdr170 · September 8, 2016

Testing 1.7 and I see the category tree always collapse after selecting a sub category, is there a way to have this remain open so you do not have to re-open menu to get to other sub categories as in 1.6.

I have looked but do not see anything, any ideas.

Vincent Beudez · September 8, 2016

Hi,

On which page please ?

tdr170 · September 8, 2016

Any page, open the menu and click on any subcategory and the menu collapses back to Women instead of staying on the subcategory.

I am testing the site in a 2 column layout so you use the left category tree all the time no top menu.

deonderd · May 4, 2017

i have the same problem..

in 1.7 the categery tree does not stay open in the category u are in..

its very confusing for customers if u have like several subcategories.. for example for mercedes -> filters -> Oilfilters

i would prefer also that the whole tree stays visible.. for easy navigating

tukker · July 6, 2017

I have the same problem. I would aso prefer the whole tree is expanded.

Haven you already found a solution ?

I have found some themes where the created this. So there must be a way to get this working

templatin · July 8, 2017

You can keep the whole tree similar on all pages by configuring the "Category tree links" module in Back-office.

Select the following option: Category root => Home category.

You can also try other options based on your requirement.

tiwelle · August 24, 2017

Have you found a way to keep the category tree open on a category page ?

@templatin, your solution is answering the question. It does have some options to configure, but what if you want to have the entire category tree (with all categories), open on current category ? That is what tdr170 is asking.

Thank you !

tiwelle · August 24, 2017

I have a solution

You can add a class to the category tree you're in by

{if $node.id == $category.id} displaymytree{/if}

Then, with Jquery, you can target all parents from this particular class

$(document).ready(function(){
	$( '.displaymytree' ).parents( ".collapse" ).addClass('displaymytree');
});

And then, force display block on all elements with that class :

.displaymytree.collapse {
    display: block;
}

Enjoy !

And where should we put that code...

Rynraf · October 28, 2017

I was trying to use this code

{if $node.id == $category.id} displaymytree{/if}

in this file /themes/classic/modules/ps_categorytree/views/templates/hook/ps_categorytree.tpl but there is an error. I'm also don't know how/where to implement this change. Could you please give some advice?
I have a feeling that if I would like to have mark selected category using some CSS class I have to use some code like above... Am I right?

What I would like to acheive is to have by default expanded all categories and subcategories. I would like to have shown, expanded all categories all the time as I have now in PS 1.6 (my shop on PS 1.6: https://palmatum.pl ). Any advice?

Now with this new PS 1.7 (not so new today...) I'm feel like years ago with OsCommerce - when I would like to have something - I have to code this by myself

Rynraf · October 31, 2017

Answer to my own question... In my Prestashop I would like to have exapned all categories all the time. I'm starting with "Classic" theme.

In file: /themes/classic/modules/ps_categorytree/views/templates/hook/ps_categorytree.tpl it's enugh to make two little changes.
In two lines (line numer 39 and 50) which looks like this:
<div class="collapse" id="exCollapsingNavbar{$node.id}">
add " in" to class atribute and add attribute "aria-expanded" with value "true". Final this two lines will look like this:
<div class="collapse in" id="exCollapsingNavbar{$node.id}" aria-expanded="true">

That's all. Upload changed file.

tantan199 · December 19, 2017

Hi,

I created a tutorial several weeks ago about the problem, check it here: how to set the Category tree links module to expand the brunch containing current category in PrestaShop 1.7,

Kunsthelden · January 9, 2018

Dear tantan199

your code works fine. The only thing that is missing for the classic theme is the collapse in. The arrows and + works fine, also after reloade but the whole navigation remains open. I still can recommend your solution.

kind regards,

tantan199 · January 11, 2018

@Kunsthelden what did you mean "the whole navigation remains open"? Can you please explain it more, so I can improve that guide.

Thanks.

Unfortunately it works not on PS 1.7.4.4.

Is there a solution?

Or can someone upload the modified files? Maybe I made something wrong?

Thanks a lot, it works perfect, the info is really useful for a 1.7.2.4. I still don't understand this lost of features between 1.6 and 1.7 ..

ciepolml · December 19, 2018

In case somebody still fights and wants a neat one .tpl file solution without CSS involved.

See my answer at the end in this thread.

Just adding"in" to one class and then {if !$_collapse} aria-expanded="true"{/if} to reverse aria status from closed to opened for icon to work correctly.

Has PS fixed this issue in 1.7.4.4?

Hello,

I have classic rocket theme, and I do it everything like in your tutorial, except one (where is span, in classic rocket there is no span in that place, and I also replace 'in' by 'show'). And now I have a problem when I click on "clothes" category, I would like to all category in clothes to be showed, but this only show category when I go to "Men".

Edit. When I change for classic theme, and do everything like in the tutorial I have the same problem

@mysz I mentioned how to expand the current category’s child categories in that tutorial, you probably didn't see that part.

hi, and you code in ps_categorytree.php?

i need show menu in category and subcategory.

tantan199 · May 5, 2020

@Alex Castillo It seems you've figured it out, let me know if you need more help.

nestorps · December 5, 2020

For everyone with this problem. You dont need to edit the core controller.

Just copy the template file modules/ps_categorytree/views/templates/hook/ps_categorytree.tpl in your theme modules themes/yourtheme/modules/ps_categorytree/views/templates/hook/ps_categorytree.tpl

edit this line with:

{foreach from=$nodes item=node}
<li>

  TO

{foreach from=$nodes item=node}
<li  class="roots" id="node-{$node.id}">

And then with jquery target de selected item and then go up to expand the div:

    if(jQuery(".category-tree").length>0){
            var id=location.href.split("/");
            id=id[id.length-1].split("-")[0];
            jQuery("#node-"+id).addClass("selected-cat"); /*class to add color to the selected item*/
            jQuery("#node-"+id).closest("div").addClass("in"); /*depends on the theme. Expand the div*/
            jQuery("#node-"+id).parents("li.roots").find(".navbar-toggler").attr("aria-expanded","true"); /*depends on the theme*/
    }

Could someone paste here ALL code from ps_categorytree.tpl after changes? On my site, that code didn't work, prestasho p1.77, template: classic

for now i have:

public function getWidgetVariables($hookName = null, array $configuration = [])
    {

        if (Configuration::get('BLOCK_CATEG_ROOT_CATEGORY') && isset($this->context->cookie->last_visited_category) && $this->context->cookie->last_visited_category) {
            $category = new Category($this->context->cookie->last_visited_category, $this->context->language->id);
            if (Configuration::get('BLOCK_CATEG_ROOT_CATEGORY') == 2 && !$category->is_root_category && $category->id_parent) {

What file does this bottom jQuery example go?

Billy · September 10, 2021

I have this example code below from the ( Main Menu in Prestashop 1.7.7.7 )

Which is called the ( ps_categorytree module )

I just want the stock menu to work

In this example I have modified the bottom of the file with the code from

https://www.sunnytoo.com/8222/how-to-set-the-category-tree-links-module-to-expand-the-brunch-containing-current-category-in-prestashop-1-7

I used his two example in my code all the way at the bottom of this post aka

Here is his example #1

$categories = $this->getCategories($category);
return [
'categories' => $categories,
'c_tree_path' => isset($categories['children']) && count($categories['children']) && method_exists($this->context->controller, 'getCategory') && ($curr_category = $this->context->controller->getCategory()) ? self::getTreePath($categories['children'], $curr_category->id) : false,
'currentCategory' => $category->id,
];

Here is the second example from Sonny's website ST Themes aka

"If you want to expand the current category's child categories, see @Pepecop's question on the comment section below, then use this getTreePath function to instead the one on the step #2."

public static function getTreePath($categories, $id, array $path = [])
{
    foreach ($categories as $cate) {
        if ($cate['id'] == $id){
            if(is_array($cate['children']) && count($cate['children']))
                $path[] = $cate['id'];
            return $path;
        }
        $path[] = $cate['id'];
        if(is_array($cate['children']) && count($cate['children'])) {
            if ($result = self::getTreePath($cate['children'], $id, $path))
                return $result;
        }
        array_pop($path);
    }
    return false;
}

I am getting a ( syntax error, unexpected 'public' (T_PUBLIC) on line ( 338, 1 )

Can anyone fix this one issue please please please. Could you fix the complete file and repost the whole file below?

I have been going around and around with this menu for two days as I'm not a coder.

Thank you in Advance!

Billy
