XF 2.1 How place custom field below title on text editor ?

[dondomainer]

have located the template containing the text editor ( name : editor ) but I'm not able to locate the code snippet that belongs to custom field.

<xf:css src="editor.less" />

<xf:if is="$fullEditorJs">
    <xf:js src="vendor/froala/froala-compiled.full.js, xf/editor.js" />
<xf:else />
    <xf:js prod="xf/editor-compiled.js" dev="vendor/froala/froala-compiled.js, xf/editor.js" />
</xf:if>
<!--[XF:include_js]-->

<xf:if is="is_editor_capable()">
