Archiving an Opportunity allows you to remove it from the list of active Opportunities and default view within your Opportunities pipeline. You may want to do this if a specific Opportunity has been inactive for an extended time period.
By default, only your active Opportunities will be displayed, but you can view your archived or all Opportunities by selecting the desired selection from the Status Filter dropdown.
How to Archive
To archive an Opportunity, hover over the Opportunity card. Upon doing so, you will se a gray box icon. If you click on the box, the Opportunity will be archived.
How to Un-Archive
When hovering over an archived Opportunity, you can move it back to the active state by clicking the gray box icon.
