Add option to disable translation links

[olafgrabienski]

We need the option to disable translation links on Backdrop4Good. (It's an important option for multilingual sites in general.)

By "translation links" I mean the language switcher links which are visible by default at the bottom of a node when there is a (published) translation of this node. Here's an example of my local Bd4Good site:

In Drupal 7, by using the "Multilingual content" submodule of the i18n module, there are two ways to disable these translation links:

• Set the "Language" (pseudo) field on the Manage display page at admin/structure/types/manage/MY-TYPE/display to "Hidden".
• Alternatively, go to the Node options tab of the Multilingual settings page at admin/config/regional/i18n/node, and enable the option "Hide content translation links".

The first way is part of Drupal 7 core, so iIt would be good to add it to Backdrop as well.

This should be fixed in Backdrop core, so here is the core issue: backdrop/backdrop-issues#2910

When the issue blocks further development we can hide the Language links via CSS as a temporary workaround. But let's see!

Sorry, the option in question is not part of Drupal 7 core, sorry for for incorrect information! (Have modified the issue description and changed the labels respectively.)

In the meantime, we have good working PR in the respective core issue. I've tagged the issue there with milestone 1.8.1 so that we can use the fix hopefully soon for Bd4Good.
