On Site Messager currently has three zones available for customization: Main, Side, and Banner. These zones can appear anywhere on your screen layout. Be sure to label each zone appropriately for easy navigation and organization in OSM.
Go to the Studio tab, then the Screen Layout tab. Choose an existing layout or create a new layout. Refer to the How to Create a Layout solution. To label a zone click the yellow gear and choose a label in the Zone Tag drop down.
Once your zones are labeled, publishing messages in OSM will be easier to navigate. Refer below to the three zones and their labels.
