You can customize the position of the switcher if you open the Switcher Configurator tab in the langify dashboard.

Position
There are three options:
Fixed - scrolls with the view
Absolute - stays in one position of the page
Custom - add a small piece of code to your theme in order to place the switcher in anywhere you want
Alignment
If you have selected the Fixed or Absolute position, then you can further adjust it by setting an alignment.
You can assign any corner left/right and top/down of the page.
