Dear Hans, Consider the following MWE with nested multi-column itemize and item label: \setuptagging[state=start] \setupinteraction[state=start] \starttext \startitemize[n] \item[label] First \startitemize[a, columns] \item Second \item Third \stopitemize \stopitemize\crlf Bla \in{Item}[label]. \stoptext The above results in a PDF whose tag tree looks as follows: ‹document› |-‹itemgroup› itemize | |-<item> | | |-‹itemtag› | | | '-"1." | | '-‹itemcontent› | | |-"First" | | '-‹itemgroup› itemize | | |-‹item› | | | |-‹itemtag› | | | | '-"a." | | | '-‹itemcontent› | | | '-"Second" | | '-‹item› | | |-‹itemtag› | | | '-"b." | | '-‹itemcontent› | | '-"Third" | '-‹link› | '-"Item 1" |-"Bla" '-"." In this tag tree, the ‹link› item is placed wrongly inside the topmost ‹itemgroup›. It sould be located between "Bla" and ".". This happens only if: 1. An itemization with multiple columns is nested in an itemization 2. Interaction is enabled. I think this is a bug. Please consider fixing it. Kind regards, Christoph
