Apps that integrate with Slack can now include drop-down menus in the messages that they post to the service, as part of a push to improve the interactivity of third-party integrations.
Slack's message menus let apps spawn clickable lists that users can choose from in order to take actions that developers have enabled. For example, using menus would allow users to pick a from a list of customers in a CRM system that integrates with Slack, assuming the developers have built their service to work with the new feature.
Developing integrations with the broader universe of enterprise software is key to Slack’s longevity. Deeper integrations with a broad third-party ecosystem can help the service compete against Microsoft Teams and Google Hangouts Chat, according to Gartner Research Vice President Mike Gotta.
