Feature attachments can play a key role in data validation, exploration, and presentation. These workflows are often aided by the pop-up. In these scenarios, viewers are shown all the attachments associated with a feature. One of the main pillars of creating great maps is only giving viewers the information they need. With all that in mind, we are excited to announce that with the October 2025 update of ArcGIS Online you will have control over which attachments are displayed in your pop-ups.<\/p>\n
