I can't add the component onto the Department Landing template.
The component is ONLY available within the Tab Item component and cannot be added to other location in the Department Landing template.
Where can I find out about recommended image size?
To find out more about the best image size for the Mosaic component, please consult the Recommended Image Size page.
I'm not able to select the Mosaic component to adjust/remove it.
To select the Mosaic component (instead of individual tile), you can first select one of the individual tile to open the Edit bar, and then click on the Parent icon (last icon in the Edit bar) to display the parent component selection screen. Choose Mosaic container and the Mosaic component will be highlighted with the Edit bar opened.
I'm not able to add the Mosaic component to a certain location.
Due to the pre-set width on the Mosaic component, it can only be added to a full-width layout.
