Each view can translate the exposed form from the Exposed Form section. This does not translate the labels on the form but the form elements. You can translate the submit button text, reset button label, sort label, and ascending or descending .
You can translate the labels for exposed filters from the Filters section. Each exposed filter will show up as a collapsible fieldset, allowing you to configure the administrative label and front-facing label.

By default, available translations need to be imported through the global interface translation context.
