[NTG-context] Re: Nested itemize

22 Aug 2023


      It seems that displaystyle fractions insert extra vertical space before the
main item.
With textstyle fractions, the code works fine.
\blank[back,overlay] can get rid of the gap above the first row, but not
the space inserted by \dfrac.


\defineitemgroup[alex]

\setupitemgroup
 [alex]
 [each]
 [a,two]
 [
 margin=2cm,
 before={\blank[overlay,-depth]},
 after={\blank[nowhite]},
 stopper=)
 ]

%\showboxes
\autofences

\starttext
\samplefile{ward}
\startitemize[n][style=\bf,before={\blank[back,overlay]},after={\blank[medium]}]
  \startitem
    \startalextable
      \startitem
        \m{6(x - \frac{5}{12})^2 - \frac{1}{24}}
      \stopitem
      \startitem
        \m{-3(x - \frac{1}{3})^2 + \frac{1}{3}}
      \stopitem
      \startitem
        \m{7(x + \frac{5}{14})^2 + \frac{199}{28}}
      \stopitem

Hi Mikael,
That looks very attractive. However, with the following code, I end up
with a large gap above the first row.
\defineitemgroup[alex]
\setupitemgroup
 [alex]
 [each]
 [a,two]
 [
 margin=2cm,
 before=\blank[overlay,-depth],
 stopper=)
 ]
\showboxes
\autofences
\starttext
\samplefile{ward}
\startitemize[n][style=\bf]
 \startitem
 \startalextable
 \startitem $6(x - \dfrac{5}{12})^2 - \dfrac{1}{24}$ \stopitem
 \startitem $-3(x - \dfrac{1}{3})^2 + \dfrac{1}{3}$ \stopitem
 \startitem $7(x + \dfrac{5}{14})^2 + \dfrac{199}{28}$ \stopitem
 \startitem $-\dfrac{1}{2}(x + 2)^2 + \dfrac{9}{2}$ \stopitem
 \stopalextable
 \stopitem
\stopitemize
\samplefile{ward}

It’s true that \vtop{…} does the job for a single line of items, but it
doesn’t in the case there’re multiple (\vtop{}) aligns with the bottom.
Here’s a modified MWE
\startitemize[n][style=\bf]
  \item \godown[-\lineheight] \startitemize
[a,columns,two,packed,broad][stopper=),before={\blank[nowhite]}]

I'd do it this way:

\item\vtop{%

Dear ConTeXt users,
Time goes by but I haven't yet found a nice solution to this issue. When
having mathematics, I'd not like to adjust by hand the factor of \linewidth
for the \godown command.
Here's a MWE
\starttext
\startitemize[n][style=\bf]
  \item \godown[-\lineheight] \startitemize
[a,columns,four,packed,broad][stopper=),before={\blank[nowhite]}]
    \item $6(x - \dfrac{5}{12})^2 - \dfrac{1}{24}$
    \item $-3(x - \dfrac{1}{3})^2 + \dfrac{1}{3}$
    \item $7(x + \dfrac{5}{14})^2 + \dfrac{199}{28}$
    \item $-\dfrac{1}{2}(x + 2)^2 + \dfrac{9}{2}$
  \stopitemize
\stopitemize
\stoptext
Thanks in advance.

Dear all,
I'm struggling to setup a nested itemize with no blank line and several
columns.
What I mean is something like
1. a) bla   c) bla
    b) bla   d) bla
The following MWE is my starting point
\starttext
\startitemize[n]
\item \blank[-line]
\startitemize[a,horizontal,two] [margin=2cm]
\item First
\item Second
\item Third
\item Fourth
\stopitemize
\item \blank[-line]
\startitemize[a,horizontal,columns,two]
\item First
\item Second
\item Third
\item Fourth
\stopitemize
\stopitemize
\stoptext
Thanks in advance
