With the introduction of the form language concept in #1498874: Provide language awareness to entity forms (introduce the form language concept), we will need a language switcher allowing to choose the form active language.
Agreement that a drop button as in #7
Done: mock ups.
Done: ui element chosen. (We need to figure out if this can be a regular language switcher block or if it will be a UI elelment placed inside the form itself.)
Done: initial implementation (proceeded since form language landed #1498874: Provide language awareness to entity forms (introduce the form language concept)).
- refine according to feedback in #32. Contributor Task to create patch: http://drupal.org/node/1424598
- (waiting on refinement) manually test, after implementation. Contributor Task to manually test: http://drupal.org/node/1489010 (be sure to note browsers used)
- final screenshots, after implementation
User interface changes
todo: clarify if there would be api changes. (API changes/additions that would affect module, install profile, and theme developers, including examples of before/after code if appropriate)
