Milliman Mind allows you to dynamically hide some rows, columns, and the headers line according to calculation results or selected dimensions/instances.
How to hide rows
To hide some columns inside a grid, you should create a new column at the right of your grid with the following header: /HideRows .
This column can contain formulas that will return for each row:
- TRUE / 1 to hide the matching row.
- FALSE / 0 to display the matching row.
For example :

Will be displayed like that in Milliman Mind.

How to hide columns
To hide columns, you should add (dynamically or not) the keyword &&HideColumn in your header name.

In this example Column 2 will be hidden.
How to hide the header line
If you want to hide the header line of a grid without the /NoHeader flag, simply add the text "&hide" to any of the header cells. It will automatically hide the full header line of the grid.
