A "mention" is triggered by a marker. You are free to choose a "marker" of your choice (this demo uses the @ symbol to trigger a "mention"). User names are stored as items in a dataSource. Data can be retrieved from multiple data sources. When using multiple data sources, you must assign an unique marker to each.
To "mention" a user, simply enter the @ symbol and select the desired record from the "Mentions" drop-down user list. Like today's most popular collaboration tools, you can enter additional characters to filter the records displayed within the "Mentions" drop-down user list.
