# No gridding for a single paragraph (ConTeXt)?

Is there a possibility to deactive grid=yes in the text for a single paragraph only? It should be something like \nogrid{ paragraph.... }. There is \placeongrid{} - but this does not allow page-breaking, so the whole paragraph is set as one on a new page, if breaking is needed. I think no minexample is needed here, any paragraph does it.

You just put stuff in a \vbox and \vsplit it to break across pages. To not mess up the gridding around, use \snaptogrid when placing the boxes.

\showgrid
\setuplayout[grid=yes]

\unexpanded\def\startnogrid{%
\setbox\scratchboxone=\vbox\bgroup}

\unexpanded\def\stopnogrid{%
\egroup
\scratchdimen=\dimexpr\pagegoal-\pagetotal-\topskip\relax
%                                          ^^^^^^^^
% This should not be \topskip but something else, but I don't know what.
\ifdim\dimexpr\ht\scratchboxone+\dp\scratchboxone\relax>\scratchdimen
\setbox\scratchboxtwo=\vsplit\scratchboxone to \scratchdimen
\snaptogrid\hpack{\box\scratchboxtwo}
\snaptogrid\hpack{\box\scratchboxone}
\else
\snaptogrid\hpack{\box\scratchboxone}
\fi}
