FAQ#
Why can the value exceed the min and max range in controlled mode?#
In controlled mode, developers may store related data by themselves. If the component constrains the data back to the range, it will cause the displayed data to be inconsistent with the actual stored data. This leads to potential data problems in some scenarios such as form fields.
