Note: Starting at ArcGIS Pro 2.9, text fields in a table display a link for text that meets a combination of URI schemes and file extensions. You can define the URI schemes and file extensions used to recognize hyperlinks in a text field. See the latest ArcGIS Pro documentation: Set options for hyperlinks in table text.
In versions 2.8.3 and prior, ArcGIS Pro allows a hyperlink path to be added to a field in the attribute table. This option adds a hyperlink for an individual feature in a feature layer, allowing access to feature-related documents, images or web pages when the pop-up window is clicked. Features without hyperlinks display null values in the hyperlink section of the pop-up window.
Follow the instructions below to insert a hyperlink path to a field:
<a href="file://filepath" target="_top">hyperlinkname</a>
