Issue Summary

The Timeline view in Business projects currently has the view option "Hide done items," which differs from the Software projects view option "Show done items (from last <number> months)."
When the option is turned off, all done items are displayed on the timeline without the option to select only past <number> months to be displayed.

Steps to Reproduce

This option can be toggled in the timeline view of JWM projects:

Expected Results

Unified functionality with option to display done items from last <number> months.

Actual Results

Displaying all done items or no done items.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
