Hide all messages in Conversation View for an easier view of all the conversation threads that occurred with a record. In contrast, show all conversations to view the message content within each conversation thread.
Hide/Show Conversation Threads
In Conversation View, click on the Hide All button on the top right hand side of the component. All conversations will be collapsed leaving the conversation thread titles, a count of the number of messages, and the date of the last message.
You can reveal your messages by clicking on the Show All button. All messages are in the normal Conversation View format.
