 | displayPriority | number | Display priority for the component in the layout container. When the space of the parent container is insufficient, the component with a lower priority is hidden.<br>The digits after the decimal point are not counted in determining the display priority. That is, numbers in the [x, x + 1) range are considered to represent the same priority. For example, **1.0** and **1.9** represent the same priority.<br>Since API version 9, this API is supported in ArkTS widgets.<br>**NOTE**<br>This attribute is valid only for the **\<Row>**, **\<Column>**, and **\<Flex>** (single-row) container components.|
