+# WaterFlow
+
+
+The **\<WaterFlow>** component is a container that consists of cells formed by rows and columns and arranges items of different sizes from top to bottom according to the preset rules.
+
+
+> **NOTE**
+>
+> This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
+
+
+## Child Components
+
+
+The [\<FlowItem>](ts-container-flowitem.md) child component is supported.
+
+
+## APIs
+
+
+WaterFlow(options?: {footer?: CustomBuilder, scroller?: Scroller})
+
+**Parameters**
+
+| Name    | Type                                       | Mandatory| Description                                    |
+| ---------- | ----------------------------------------------- | ------ | -------------------------------------------- |
+| footer |  [CustomBuilder](ts-types.md#custombuilder8) | No  | Footer of the **\<WaterFlow>** component. |
+| scroller | [Scroller](ts-container-scroll.md#scroller) | No  | Controller, which can be bound to scrollable components.<br>The **\<WaterFlow>** component supports only the **scrollToIndex** API of the **\<Scroller>** component.|
+
+
+## Attributes
+
+
+In addition to the [universal attributes](ts-universal-attributes-size.md), the following attributes are supported.
+
+| Name| Type| Description|
+| -------- | -------- | -------- |
+| columnsTemplate | string | Number of columns in the layout. If this attribute is not set, one column is used by default.<br>For example, **'1fr 1fr 2fr'** indicates three columns, with the first column taking up 1/4 of the parent component's full width, the second column 1/4, and the third column 2/4. This attribute supports [auto-fill](#auto-fill).<br>Default value: **'1fr'**|
+| rowsTemplate | string | Number of rows in the layout. If this attribute is not set, one row is used by default.<br>For example, **'1fr 1fr 2fr'** indicates three rows, with the first row taking up 1/4 of the parent component's full height, the second row 1/4, and the third row 2/4. This attribute supports [auto-fill](#auto-fill).<br>Default value: **'1fr'**|
+| itemConstraintSize | [ConstraintSizeOptions](ts-types.md#constraintsizeoptions) | Size constraints of the child components during layout.              |
+| columnsGap | Length |Gap between columns.<br>Default value: **0**|
+| rowsGap | Length |Gap between rows.<br> Default value: **0**|
+| layoutDirection | [FlexDirection](ts-appendix-enums.md#flexdirection) |Main axis direction of the layout.<br>Default value: **FlexDirection.Column**|
+
+The priority of **layoutDirection** is higher than that of **rowsTemplate** and **columnsTemplate**. Depending on the **layoutDirection** settings, there are three layout modes:
+
+- **layoutDirection** is set to **FlexDirection.Column** or **FlexDirection.ColumnReverse**
+
+	In this case, **columnsTemplate** is valid. If it is not set, the default value is used. For example, if **columnsTemplate** is set to **"1fr 1fr"** and **rowsTemplate** **"1fr 1fr 1fr"**, child components are arranged in vertical layout, with the cross axis equally divided into two columns.
+
+- **layoutDirection** set to **FlexDirection.Row** or **FlexDirection.RowReverse**
+
+	In this case, **rowsTemplate** is valid. If it is not set, the default value is used. For example, if **columnsTemplate** is set to **"1fr 1fr"** and **rowsTemplate** **"1fr 1fr 1fr"**, child components are arranged in horizontal layout, with the cross axis equally divided into three columns.
+
+- **layoutDirection** is not set
+
+	In this case, the default value of **layoutDirection** is used, which is **FlexDirection.Column**, and **columnsTemplate** is valid. For example, if **columnsTemplate** is set to **"1fr 1fr"** and **rowsTemplate** **"1fr 1fr 1fr"**, child components are arranged in vertical layout, with the cross axis equally divided into two columns.
+
+## Events
+
+
+In addition to the [universal events](ts-universal-events-click.md), the following events are supported.
+
+
+| Name| Description|
+| -------- | -------- |
+| onReachStart(event: () => void) | Triggered when the component reaches the start.|
+| onReachEnd(event: () => void)   | Triggered when the component reaches the end.|
+
+
+## auto-fill
+
+The **columnsTemplate** and **rowsTemplate** attributes supports **auto-fill** in the following format:
+
+```css
+repeat(auto-fill, track-size)
+```
+
+Where, **repeat** and **auto-fill** are keywords, and **track-size** indicates the row height or column width. The supported units include px, vp, %, and digits. The value of **track-size** must contain at least one valid row height or column width.
+
+
+## Example
+
+
+```ts
+// WaterFlowDataSource.ets
+
+// Object that implements the IDataSource API, which is used by the <WaterFlow> component to load data.
