The External link field is an easy way to add a reference to an external Kanbanize source.
Tip: You can use the default external link field to link Kanbanize as a tracking software to your Local file server or a SharePoint server.
Note that due to the browser’s restrictions, you have to copy/paste the link into the file Explorer.
To make the external link visible on the initial card view -> use the grid menu at the upper right corner of your board interface -> select Configure Card View.
Select Show external link (Icon or Full text) from the Card/Board settings panel.
This action makes the external link field visible in the initial card view, so every user can easily open the link without opening the card.
