Right-to-Left Support

Right-to-Left Support

The DevExtreme Editor components support right-to-left (RTL) languages. The components can display content in a right-to-left direction and mirror associated UI elements.

To enable RTL language support in the application, you can either set the globalConfig object's rtlEnabled property to true or specify each component's rtlEnabled property individually. Note that individual RTL parameters have higher priority than general parameters.

In this demo, you can use the language drop-down menu (for example, change the language from English to Arabic) to explore the differences between default and RTL modes.
