Step 3

Update: style.css

/* FOR bulk_action_toolbar */
#bulk_delete_form,
#bulk_duplicate_form {
  display: none;
}

#bulk_action_toolbar {
  display: none;
  align-items: center;
  gap: 1rem;
  background-color: #f9fafb;
  padding: 0.5rem 1rem;
  border: 1px solid #e5e7eb;
  border-radius: 8px;
  box-shadow: 0 2px 4px rgba(0,0,0,0.04);
  margin: 1rem 0;
}

}

.action_button:hover {
  background-color: #2563eb;
}

#bulk_action_toolbar img {
  height: 18px;
  transition: opacity 0.2s ease;
}

#bulk_action_toolbar img:hover {
  opacity: 0.7;
}

/* FOR bulk_action_toolbar */

}

#bulk_action_toolbar img {
  height: 18px;
  transition: opacity 0.2s ease;
}

#bulk_action_toolbar img:hover {
  opacity: 0.7;
}

Step 4

Update: OptionController.php
Add 2 new functions:
1. delete_multiple()
2. duplicate_multiple()

function delete_multiple() {
    $this->_checkPermission();

    if (!isset($_POST['ids']) || empty($_POST['ids'])) {
        Flash::set('error', __('No options selected for deletion.'));
        redirect(get_url('option'));
    }

    $ids = explode(',', $_POST['ids']);
    $deleted = 0;

    foreach ($ids as $id) {
        $option = Option::findById((int)$id);
        if ($option && $option->delete()) {
            $deleted++;
        }
    }

    if ($deleted > 0) {
        Flash::set('success', "$deleted option(s) deleted successfully.");
    } else {
        Flash::set('error', 'No options were deleted.');
    }

    redirect(get_url('option'));
}

function duplicate_multiple() {
    $this->_checkPermission();

    if (!isset($_POST['ids']) || empty($_POST['ids'])) {
        Flash::set('error', __('No options selected for duplication.'));
        redirect(get_url('option'));
    }

    $ids = explode(',', $_POST['ids']);
    $duplicated = 0;

    foreach ($ids as $id) {
        $option = Option::findById((int)$id);
        $option->name = '(Copy of) ' . $option->name;
        $option->code = '(Copy of) ' . $option->code;
        $option->created_by_id = AuthUser::getId();
        $option->created_on = date('Y-m-d H:i:s');
        $option->updated_by_id = null;
        $option->updated_on = null;
        if ($option && $option->duplicate()) {
            $duplicated++;
        }
    }

    if ($duplicated > 0) {
        Flash::set('success', "$duplicated option(s) duplicated successfully.");
    } else {
        Flash::set('error', 'No options were duplicated.');
    }

    redirect(get_url('option'));
}

function delete_multiple() {
    $this->_checkPermission();

    if (!isset($_POST['ids']) || empty($_POST['ids'])) {
        Flash::set('error', __('No options selected for deletion.'));
        redirect(get_url('option'));
    }

    $ids = explode(',', $_POST['ids']);
    $deleted = 0;

    foreach ($ids as $id) {
        $option = Option::findById((int)$id);
        if ($option && $option->delete()) {
            $deleted++;
        }
    }

    if ($deleted > 0) {
        Flash::set('success', "$deleted option(s) deleted successfully.");
    } else {
        Flash::set('error', 'No options were deleted.');
    }

    redirect(get_url('option'));
}

function duplicate_multiple() {
    $this->_checkPermission();

    if (!isset($_POST['ids']) || empty($_POST['ids'])) {
        Flash::set('error', __('No options selected for duplication.'));
        redirect(get_url('option'));
    }

    $ids = explode(',', $_POST['ids']);
    $duplicated = 0;

    foreach ($ids as $id) {
        $option = Option::findById((int)$id);
        $option->name = '(Copy of) ' . $option->name;
        $option->code = '(Copy of) ' . $option->code;
        $option->created_by_id = AuthUser::getId();
        $option->created_on = date('Y-m-d H:i:s');
        $option->updated_by_id = null;
        $option->updated_on = null;
        if ($option && $option->duplicate()) {
            $duplicated++;
        }
    }

    if ($duplicated > 0) {
        Flash::set('success', "$duplicated option(s) duplicated successfully.");
    } else {
        Flash::set('error', 'No options were duplicated.');
    }

    redirect(get_url('option'));
}
