I'm not sure but if the concern is only the visible “Without type” heading, the following template override can be used as a temporary workaround.
1. Log in to the Joomla administrator.
2. Go to:
System → Site Templates → Site Template Styles
3. Open the active site template.
4. Select the tab:
Create Overrides
5. Under Components, select:
com_jem → categories
Joomla should create the override files in:
/templates/YOUR_TEMPLATE/html/com_jem/categories/
Depending on the selected JEM layout, check one or both of these files:
default.php
responsive/default.php
6. Search for:
Text::_('COM_JEM_TYPECATEGORIES_UNASSIGNED')
It should be part of a section similar to this:
return '<div class="jem-type-section-header"><h2 class="jem-type-section-title">'
. Text::_('COM_JEM_TYPECATEGORIES_UNASSIGNED')
. '</h2></div>';
7. Replace that return statement with:
return '';
For example:
$renderTypeSectionHeader = function ($type) use ($buildTypeBadge) {
if ($type) {
return '<div class="jem-type-section-header"><h2 class="jem-type-section-title">'
. $buildTypeBadge($type)
. '</h2></div>';
}
return '';
};
8. Save the override and clear the Joomla and browser cache.
This removes the complete “Without type” heading, including its empty heading container and possible spacing.
Important:
This is only a local workaround. It should not be applied directly to the JEM component files, because those changes would be overwritten by a JEM update.
