OpenCms 9.5 introduces nested containers, which provide developers a range of powerful new template options. Nested containers can for example be used to create a tab element with a defined list of tab headings but flexible tab contents that can be added by drag & drop. It’s even possible to use nested containers to generate a grid structure for template models starting with a “blank sheet of paper”. In this session, Andreas explains how nested containers can be defined in a formatter. He demonstrates how to generate different container configurations based on the formatter settings. Moreover, he shows how elements placed in nested containers can interact with the container to adjust their output according to the requirements of the page layout.
