The standard list item can contain an icon (in the form of an image or from the SAP icon font), a title (left-aligned), a short description (left-aligned below the title), and a semantic info text (right-aligned next to the description).
The title and description truncate and do not wrap. The info does not wrap or truncate, so it causes the title or description (when used) to truncate. Therefore, try to keep all texts as short as possible and only as long as is really necessary to understand the content.
By default, the title font is larger if the description is empty. If you have list items with and without a description, this results in differently sized titles, which makes it harder to read. In this case, you should switch off the title size adaptation (AdaptTitleSize).
