Hi Davy,
Thanks for contacting Syncfusion support.
We checked your query and would like to mention that currently we have not provided support for setting multiple ranges with Range Slider component.
However, “Provide multiple range support in Range Slider” had already been considered as a feature from our end. This will be included in any one of our upcoming releases. Generally, we will plan the feature implementation based on feature rank, wishlist plan and customer request count.
You can track the feature status through the below feedback link.
Please get back to us if you need any further assistance.
Regards,
Sharon Sanchez S.
