Specifies if free-form layout is enabled. This layout mode allows dashboard panels to be placed wherever desired by the user, instead of fitting into a columnar arrangement. When disabled, users must arrange panels in pre-defined columns.
When set to True, "Free-form" is available as one of the "Number of Panel Columns" options in the dashboard configuration page. If the user then selects this option at runtime, he can manually relocate and resize dashboard panels anywhere within the dashboard, without being constrained by pre-defined columns.
Default value is "False".
