In the above posted code in the local!array I have generated the array, you can simply initialize the array of integer you need and the code will work.

what's the way to make it 2 dimensional ?

Sure. Appian automatically merges your values into a one-dimensional list.

Hi Stefan, I wrote this code to print things in above format

a!localVariables(
local!array:{{1,2,3},{4,77,88},{77,88}},
{
a!forEach(
items: local!array,
expression: a!sectionLayout(divider: "BELOW",contents: {a!forEach(
items: fv!item,
expression: a!richTextDisplayField(
value: a!richTextItem(
text: fv!item
)
)
)})
)

}
)

But it is giving output like this

In this blog post

I describe how to turn a list into a two-dimensional matrix. Then you can just run two nested foreach() loops to output the values in any way you like.

umm that should not be the case. I want to pass value in array.. and suppose the array will be like this : {21,26,27,28,30,36,1,2,5,199,200}..
Then it will not work

No, It is just integer.

a!localVariables(
  local!array: enumerate(ri!input) + 1,
  local!cardsPerRow: 5,
  local!numOfRows: tointeger(
    ceiling(
      count(local!array) / local!cardsPerRow,
      .5
    )
  ),
 a!columnLayout(
      contents: {
        a!forEach(
          items: enumerate(local!numOfRows) + 1,
          expression: a!localVariables(
            local!rowIndex: fv!index,
            a!columnsLayout(
              columns: a!forEach(
                items: enumerate(local!cardsPerRow) + 1,
                expression: a!localVariables(
                  local!colIndex: local!cardsPerRow * local!rowIndex - local!cardsPerRow + fv!index,
                  local!entityIdForColIndex: index(local!array, local!colIndex, null()),
                  a!columnLayout(
                    contents: a!richTextDisplayField(
                      value: a!richTextItem(
                        text: index(
                          local!array,
                          local!entityIdForColIndex,
                          null()
                        )
                      )
                    )
                  )
                )
              )
            )
          )
        )
      }
    )
  
)

I think the above code will work dynamically for your requirement.

Just use two nested foreach loops, just like in any other programming language. Give it a try, and we can help you in case you have a specific question.
