# Flex
> **NOTE**<br/>
> This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version.
The **\<Flex>** component allows for elastic layout of child components.
> **NOTE**
> - This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version.
> - The **\<Flex>** component adapts the layout of flex items to comply with the **flexShrink** and **flexGrow** settings. This may affect the performance. Therefore, you are advised to use **[Column](ts-container-column.md)** or **[Row](ts-container-row.md)** instead under scenarios where consistently high performance is required.

| -------- | -------- |
| NoWrap | The child components in the **&lt;Flex&gt;** component are arranged in a single line, and they may overflow. |

| End | The child components are aligned with the end edge of the main axis. The last component is aligned with the main-end, and other components are aligned with the next one. |
| SpaceBetween | The child components are evenly distributed along the main axis. The first component is aligned with the main-start, the last component is aligned with the main-end, and the remaining components are distributed so that the space between any two adjacent components is the same. |
| SpaceAround | The child components are evenly distributed along the main axis, with a half-size space on either end. The space between any two adjacent components is the same. The space between the first component and main-start, and that between the last component and cross-main are both half the size of the space between two adjacent components. |
| SpaceEvenly | The child components are equally distributed along the main axis. The space between the first component and main-start, the space between the last component and main-end, and the space between two adjacent components are the same. |
