This is reviving an older idea that aged out of the consideration process: https://ideas.iii.com/forums/951979-vega-mobile/suggestions/47199707-translate-search-filter-dropdown-options-in-innova

Filter options display only in English and are not customizable. If translation strings could be added for filter options, it would not only provide libraries with the option to customize the exact wording to match what they use elsewhere outside of the app, but it would allow us to provide much better services to patrons who don't read English. In the city where my library is located, the MAJORITY of households speak a language other than English at home. Providing multilingual support is a key feature for our patrons.
