# Column freezing
Column freezing locks specific columns of a grid in place, keeping them visible while scrolling to another area of the grid. We refer to frozen columns as fixed. Columns can be frozen during initialization and by the user.
# Freeze columns at initialization
To freeze the columns on the left-hand side, you need to pass the option
fixedColumnsStart in the Settings object. The container you initialize the data grid in will need additional CSS attributes configured:
fixedColumnsStart property used to be called
fixedColumnsLeft before Handsontable 12.0.0. The old name
fixedColumnsLeft works in the LTR layout direction but throws an error when the layout direction is set to RTL.
# User-triggered freeze
To manually freeze a column, you need to set the
manualColumnFreeze config item to
true in the Handsontable initialization. When the Manual Column Freeze plugin is enabled, you can freeze any non-fixed column and unfreeze any fixed column in your Handsontable instance using the Context Menu.
A frozen column won't go back to the original position after you unfreeze it.
