Some workgroups want to maintain their webpages in English only. This is possible, but you should observe a few guidelines.
For the pages in English a complete second CMS path has to be created and maintained under physik/en/einrichtungen/ag/ag-xxxx. It is essential that the English language version is located in this path !
Many workgroups want to maintain an English version only. This is, of course, possible, but a German index page with a summary of main research topic(s) should exist. You will find an example here. A textbox has been created on the right side of the start page with links to the English content.
On our sample page you will find instructions under item 5 of the comments of how to integrate such a box in your German index page.
