How to Partition rest rows by the first row?
$begingroup$
Given a list
lst = {{{"1","2","3"},{"4","5"},{"6","7","8","9"}},
{ "A","B","C","D","E","F","G","H","I"},
{ "9","8","7","6","5","4","3","2","1"}};
How to get this by Partition
.
res = {{{"1","2","3"},{"4","5"},{"6","7","8","9"}},
{{"A","B","C"},{"D","E"},{"F","G","H","I"}},
{{"9","8","7"},{"6","5"},{"4","3","2","1"}}};
Thanks!

lst2 = lst;
lst2[[2 ;;]] = TakeList[Flatten @ #, Length /@ lst[[1]]] & /@ lst[[2 ;;]];
lst2
{{{"1", "2", "3"}, {"4", "5"}, {"6", "7", "8", "9"}},
{{"A", "B",
"C"}, {"D", "E"}, {"F", "G", "H", "I"}},
{{"9", "8", "7"}, {"6",
"5"}, {"4", "3", "2", "1"}}}
Also:
lst3 = lst;
lst3[[2 ;;]] = Function[x, Module[{k = 0}, Map[x[[k++]] &, lst[[1]], {-1}]]] /@ Rest[lst3];
lst3
same result
MapAt[TakeList[Flatten @ #, Length /@ lst[[1]]] &, lst, {{2}, {3}}]
same result

The following also works. I removed the brackets
