Hi,
In application/config/generated_overrides/site.php, I had “h5” and it’s ok for me (v9.02) :
`return [
'sites' => [
'default' => [
'editor' => [
'ckeditor4' => [
'custom_config_options' => [
'format_tags' => 'p;h2;h3;h5',
],
],
],
],
],
];
For personnal blocks, i had to limitated functionnality, I make it like this :
$editor = \Core::make('editor');
$editor->getPluginManager()->deselect(array('sourcedialog','sourcearea','tableresize','tableselection','tabletools','table','image'));
echo $editor->outputEditorWithOptions('texte[]', array(), $texte);
Hope it helps.
