Problem: The client wants to display language switch links as 'DE | EN' in the navigation bar, but currently, they appear as separate links 'English' 'German'. The client is looking for a way to add the language switch as an HTML widget in the navigation bar and to display the links together without too much space in between. Solution: To display the language names in the desired format ('DE' instead of 'German', etc.), you should go to WPML > Languages > Edit Languages and rename the languages as needed, then save the changes. To add a vertical line between the language switch links, we recommend checking out the following public tickets for guidance on adding a vertical line to the language switcher separator: here.
