Alignment: tcolorbox in enumeration

Question

How can I align the bullet of the enumeration at the top of the tcolorbox?

Answer 1

Initially tcolorboxes are aligned at the bottom, i.e. box align=bottom is set, but here, it should be aligned at the top, so use box align=top in the options of \tcbsidebyside.

  \draw[step=1,help lines,black!20] (-0.95,-0.95) grid (8.95,8.95);
  \draw[thick,->] (-1,0) -- (9,0) node[pos=0.97,below] {$x$};
  \draw[thick,->] (0,-1) -- (0,9) node[pos=0.97,left] {$y$};
  \foreach \x/\xtext in {1,2,...,8}
      \draw[shift={(\x,0)}] (0pt,4pt) -- (0pt,-4pt) node[below] {$\xtext$};
  \foreach \y/\ytext in {1,2,...,8}
      \draw[shift={(0,\y)}] (4pt,0pt) -- (-4pt,0pt) node[left] {$\ytext$};
  \node[below right] at (0,0) {0};
  \end{tikzpicture}
\item
  \tcbsidebyside[box align=top,sidebyside adapt=left, blanker, sidebyside gap=1cm, 
                 sidebyside align=top seam]{%
