I'm working on a override for com_tags List of all Tags, i want to change when clicking on the tag title the list of items (articles) will slide (accordion) instead of open in a new page. I create all the css and layout but i can't get the list for each tag. Tag list override Accordion

This the layout for *._items.php:

/**

 * @subpackage  com_tags

JHtml::_('behavior.core');
JHtml::_('formbehavior.chosen', 'select');

// Get the user object.
$user = JFactory::getUser();

// Check if user is allowed to add/edit based on tags permissions.
$canEdit      = $user->authorise('core.edit', 'com_tags');
$canCreate    = $user->authorise('core.create', 'com_tags');
$canEditState = $user->authorise('core.edit.state', 'com_tags');

$n = count($this->items);

?>
<div class="accordion" id="accordionTags">
    <?php if ($this->items == false || $n === 0) : ?>
        <p><?php echo JText::_('COM_TAGS_NO_TAGS'); ?></p>
    <?php else : ?>
        <?php foreach ($this->items as $i => $item) : ?>
            <?php if ((!empty($item->access)) && in_array($item->access, $this->user->getAuthorisedViewLevels())) : ?>

    <?php endif; ?>
    <?php // Add pagination links ?>

        <?php if (($this->params->def('show_pagination', 2) == 1 || ($this->params->get('show_pagination') == 2)) && ($this->pagination->pagesTotal > 1)) : ?>

            </div>
        <?php endif; ?>
    <?php endif; ?>
</div>

And for the list of articles(loadTemplate('items_tag')):

    <?php
    defined('_JEXEC') or die;

JHtml::_('behavior.core');
JHtml::_('formbehavior.chosen', 'select');

$n         = count($this->items);
$listOrder = $this->escape($this->state->get('list.ordering'));
$listDirn  = $this->escape($this->state->get('list.direction'));

$articleTag = new JHelperTags;
$articleTag->getItemTags('com.content.article', $item->id);

JFactory::getDocument()->addScriptDeclaration("
        var resetFilter = function() {
        document.getElementById('filter-search').value = '';
    }
");

?>
<div id=tagtest>
    <?php echo JLayoutHelper::render('joomla.content.tags', $articleTag->itemTags); ?>
</div>

<ul>
    <?php foreach ($this->items as $i => $item) : ?>
        <?php if ($this->items[$i]->core_state == 0) : ?>
            <li class="system-unpublished cat-list-row<?php echo $i % 2; ?>">
        <?php else : ?>
            <li class="cat-list-row<?php echo $i % 2; ?>">
        <?php endif; ?>
                <a href="<?php echo JRoute::_(TagsHelperRoute::getItemRoute($item->content_item_id, $item->core_alias, $item->core_catid, $item->core_language, $item->type_alias, $item->router)); ?>">
                        <?php echo $this->escape($item->core_title); ?>
                    </a>
                    <?php if ($item->core_state == 0) : ?>
                        <span class="list-published label label-warning">
                            <?php echo JText::_('JUNPUBLISHED'); ?>
                        </span>
                    <?php endif; ?> -->
            </li>
    <?php endforeach; ?>
</ul>

Use Tag model.

$tagModel = JModelLegacy::getInstance('Tag', 'TagsModel', array('ignore_request' => true));
$tagParams = new \Joomla\Registry\Registry();
$tagModel->setState('params', $tagParams);
$tagModel->setState('tag.id', $item->id);
$tagItems = $tagModel->getItems();

First, some explanations of your code. Since this is done inside tag loop ($this->items holds tags), $item variable is current tag in the loop. So this tries to get article tags but you're inputting tag ID as article ID:

$articleTag = new JHelperTags;
$articleTag->getItemTags('com.content.article', $item->id);

Anyways, you don't need this unless you also want article tags displayed so structure would be like this: Tag -> Article -> Article Tags.

Using $this->items inside items_tag layout means running the same tag loop again. Instead you need to get tagged items.

This is what my snippet does. Place it somewhere in the tag loop (items_tag layout is fine). and use $tagItems to access tagged items.

This is a what items_tag layout could look like:

<?php

defined('_JEXEC') or die;

$tagModel = JModelLegacy::getInstance('Tag', 'TagsModel', array('ignore_request' => true));
$tagParams = new \Joomla\Registry\Registry();
$tagModel->setState('params', $tagParams);
// Set tag filter
$tagModel->setState('tag.id', $item->id);
$tagItems = $tagModel->getItems();

if (!empty($tagItems)) : ?>
    <ul>
        <?php foreach ($tagItems as $i => $tagItem) : ?>
            <?php if ($tagItem->core_state == 0) : ?>
                <li class="system-unpublished cat-list-row<?php echo $i % 2; ?>">
            <?php else : ?>
                <li class="cat-list-row<?php echo $i % 2; ?>">
            <?php endif; ?>
                    <a href="<?php echo JRoute::_(TagsHelperRoute::getItemRoute($tagItem->content_item_id, $tagItem->core_alias, $tagItem->core_catid, $tagItem->core_language, $tagItem->type_alias, $tagItem->router)); ?>">
                            <?php echo $this->escape($tagItem->core_title); ?>
                        </a>
                        <?php if ($tagItem->core_state == 0) : ?>
                            <span class="list-published label label-warning">
                                <?php echo JText::_('JUNPUBLISHED'); ?>
                            </span>
                        <?php endif; ?>
                </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>
