**Name**- Group.Columns -- define group columns
**Function**-
Indicate number of columns in a two dimensional group.
If you use this tag, the total number of children must
be dividable by the number of columns.
The children will be positioned in a two dimensional array, e.g. allowing easy creation of button fields (maybe for calculator).

The children of your group are always read line by line.

When MUI layouts two-dimensional groups, it does actually two layout calculations, one for the rows and one the columns. Parameters like weights and dimensions are handled this way:

- – the minimum width of a column/row is the maximum
minimum width of all objects in this column/row.
- – the maximum width of a column/row is the minimum
maximum width of all objects in this column/row.
- – the weight of a column/row is the sum of all objects in this column/row.

- – the minimum width of a column/row is the maximum
minimum width of all objects in this column/row.
