Hi, a simple fix for the new “horizontal” optional for itemgroups: \def\strc_itemgroups_collected_flush_horizontal {\begingroup \scratchcounter\itemgroupparameter\c!n\relax \ifnum\c_strc_itemgroups_collected_done>\plusone \ifcase\modulonumber\scratchcounter\c_strc_itemgroups_collected_done\relax % compensate for rounding errors \hfill % \hskip\zeropoint plus \scaledpoint minus \scaledpoint \allowbreak \fi \fi \noindent % no \dontleavehmode - \hbox to \dimexpr\availablehsize/\scratchcounter\relax{\collecteditemgroupitem}% + \hbox to \dimexpr\availablehsize/\scratchcounter\relax{\collecteditemgroupitem\hss}% \endgroup} Wolfgang
