Unfortunately you misunderstood me. What I want to do is to override drawers export to exclude some predefined drawers. Let's say: LOGBOOK and CLOCKTABLE. Then I want to attach these drawers to headline(!) This is why I want to add a piece of code to return drawer in org-html-headline. > >> I just want to export drawer with some specific name.

I want to hard-code these drawers and ignore them in default export. Anyway thing is that I want to export drawer with specific name while I'm in org-html-headline function. (defun org-html-headline (headline contents info) "Transcode a HEADLINE element from Org to HTML. CONTENTS holds the contents of the headline. INFO is a plist holding contextual information." ;; Empty contents? (setq contents (or contents "")) (let* ((numberedp (org-export-numbered-headline-p headline info)) (level (org-export-get-relative-level headline info)) And here I wan't to add: (clocktable (and (plist-get info :with-drawers) (let* ((drawers (org-element-map headline 'drawer 'identity info nil 'headline))) (mapconcat (lambda (d) (when (string= (org-element-property :drawer-name d) "CLOCKTABLE") (org-export-data-with-backend d 'html info))) drawers "")))) In this way I could attach HTML code with CLOCKTABLE drawer to headline. Unfortunately as I mentioned before I don't know how to achieve this without recursion. My code returns all CLOCKTABLE drawers in child tasks. org-element-map has optional argument 'no-recursion' but I don't know how to set it up properly. Regards, -- Marcin
