Hi @snehankekre, a small enhancement suggestion: Would an orientation parameter help? So that the divider can either be horizontal / vertical? This has use when used with columns. For vertical, the line can extend to the height of the row.

Cheers

I suppose dividers can only be horizontal. To have it vertically you could apply a border on either the right side of the first column div, or the left side of the second column div.
