Few options are staying hidden and hints are also not present in layout builder custom block

Hi
I have reproduced the issue on Drupal 11.x and MR applied successfully;
but issue still persist with patch

Attaching screenshot for reference

Sorry confused by this MR. Core doesn’t take in custom modules

Fixed by adding a conditional UI hint that appears only for WYSIWYG inline blocks.
/**
* Implements hook_form_FORM_ID_alter() for layout_builder_add_block form.
*/
function layout_builder_form_layout_builder_add_block_alter(array &$form, &$form_state, $form_id) {
$storage = $form_state->getStorage();
$plugin_id = '';

if (isset($storage['layout_builder__component']) && is_object($storage['layout_builder__component'])) {
$component = $storage['layout_builder__component'];
// Get the block plugin ID from the SectionComponent.
if (method_exists($component, 'getPluginId')) {
$plugin_id = $component->getPluginId();
}
}

// Define the block plugins where hint is needed.
$wysiwyg_blocks = [
'inline_block:basic',
'inline_block:disclaimer_block',
];

// If current block is in the list, show the hint.
if (in_array($plugin_id, $wysiwyg_blocks) && isset($form['settings']['block_form'])) {
$form['settings']['block_form']['#prefix'] = '

';
}
}

I don’t think adding a hook is the right approach. Should find in the code where this is happening and fix at the root

Understood, will check if it’s possible to add this at the plugin level instead of using a form alter hook.

This is my proposed solution (Video layout_builder.mp4 attached for reference).
- Adds a "View more" tooltip above the CKEditor 3-dots ("Show more items") button as a hint,
- When clicked, stacks the dropdown buttons vertically — also hides unwanted separators
- Make the "Show more" dropdown cleaner and readable in narrow sidebars.
Would love your feedback on this

Why though through a hook and not directly into src code?

MR is ready for review!

also don't think aftermarket js is the approach to take but will also need tests. Also is this AI generated js?
