I like to add a block on top order creation page, in /Vendor/Module/view/adminhtml/layout/sales_order_create_index.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<css src="Amanweb_Custcomment/css/custcomment.css"/>
</head>
<body>
<referenceBlock name="content">
<block class="Vendor\Module\Block\Adminhtml\Order\View\Custcomment" before='-' name="items" ifconfig="custcomment/general/enable" template="order/view/custcomment.phtml" />
</referenceBlock>
</body>
</page>
But nothing is shown.
PS: I successfully added the same block in order view page In Vendor/Module/view/adminhtml/layout/sales_order_view.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<css src="Amanweb_Custcomment/css/custcomment.css"/>
</head>
<body>
<referenceBlock name="content">
<block class="Vendor\Module\Block\Adminhtml\Order\View\Custcomment" before='-' name="custcomment" ifconfig="custcomment/general/enable" template="order/view/custcomment.phtml" />
</referenceBlock>
</body>
</page>
