1. How to use the "External link" field of the card?
The External link field is an easy way to add a reference link to an external source of information.
Important: You can use the default External link field to link Kanbanize as a tracking software to your Local file server or a SharePoint server.
For example:
Card Title: Review Customer Contract
External Link: smb://intranet/fileserver/contracts/c03345.doc
2. How to make the "Еxternal link" visible at the closed card view?
To make the external link visible at the initial card view -> go to the sidebar at the right side of your board interface and click on the Configure Card View icon to open the Card settings panel -> select Show external link (Icon or Full text).
This will make the external link field visible at the closed card view, so every user can easily use the link without opening the card.
