List- and single-views are rendered by the extension Browser - responsive TYPO3 without PHP.
You can control the properties of list- and single-views by the Browser user-interface.
Each page, which displays list- and single-views, contains the Browser user-interface.
Please select this user-interface - called plugin - and change the properties for your needs.
The user-interface should be self-explanatory.
Precondition for a proper running Browser plugin is a proper TypoScript-template.
It is the job of your TYPO3-integrator, to take care of this proper TypoScript-template.
