we have a URL (UNC path to htm doc, but I assume it is the same for http) in some class properties and within the Operations Console they show up as clickable hyperlink.
In the dashboards, however, they are just shown as plain text.
Create a new perspective and add a HTML tile, ensure you select URL from the content settings. Use the property in mustaches, as mentioned above: I’ve used {{displayName}} as we don’t have a property with a URL:
You can also create a clickable – Just choose HTML in the content instead, using the same steps above:
Editing the core perspectives isn’t advisable, especially ones that are displayed for all objects (target = object). You can however easily create a new tile on a perspective that maps to this property and displays the page listed in that property. I’ve added to the answer above.
