Cloud and self-hosted deployments
From Mattermost v10.9, users with admin permissions can enable channel banners to remind channel members about being diligent to avoid data spillage in channels that aren’t intended for classified or sensitive information. These non-dismissible banners can be styled using Markdown and are visible across all Mattermost clients, including web browsers, the desktop app, and the mobile app.
Channel banner use cases include the following:
Security classifications, such as CONTROLLED UNCLASSIFIED: IMPACT LEVEL 5 with a distinctive color to alert members of the required security level.
Important notices, such as Reminder: Code complete deadlines are Fridays at 3 PM, for recurring reminders.
Policy or terms, such as All discussion in this channel is private and restricted with a red color to signal caution.
Mattermost channel admins, team admins, and system admins can enable a banner with custom text at the top of Mattermost public or private channels.
Create a channel banner:
Open a channel where you have administrative permissions.
Select the channel name at the top of the center pane to access the drop-down menu, then select Channel Settings.
Select Configuration and enable the Channel Banner option.
Specify the banner text you want to display at the top of the channel. You can style the text using Markdown, if desired.
Select the banner color.
Select Save to apply the changes. The banner displays immediately.
