Right-to-Left Support

Right-to-Left Support

DevExtreme Data Editor JavaScript components fully support RTL languages. As is illustrated in this demo, Editor components are able to display their contents in a right-to-left direction and fully mirror associated UI elements. Use the language drop-down menu (change from English to Arabic) to explore the differences between default and RTL modes available in DevExtreme.
