-
-**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.
-

-
-
-## 属性
-
-
-除支持[通用属性](ts-universal-attributes-size.md)外，还支持以下属性：
-
-| 名称 | 参数类型 | 描述 |
-| -------- | -------- | -------- |
-| columnsTemplate | string | 设置当前瀑布流组件布局列的数量，不设置时默认1列。<br/>例如, '1fr 1fr 2fr' 是将父组件分3列，将父组件允许的宽分为4等份，第一列占1份，第二列占1份，第三列占2份。并支持[auto-fill](#auto-fill说明)。<br>默认值：'1fr' |
-| rowsTemplate | string | 设置当前瀑布流组件布局行的数量，不设置时默认1行。<br/>例如, '1fr 1fr 2fr'是将父组件分三行，将父组件允许的高分为4等份，第一行占1份，第二行占一份，第三行占2份。并支持[auto-fill](#auto-fill说明)。<br/>默认值：'1fr' |
-| itemConstraintSize | [ConstraintSizeOptions](ts-types.md#constraintsizeoptions) | 设置约束尺寸，子组件布局时，进行尺寸范围限制。               |
-| columnsGap | Length |设置列与列的间距。 <br>默认值：0|
-| rowsGap | Length |设置行与行的间距。<br> 默认值：0|
-| layoutDirection | [FlexDirection](ts-appendix-enums.md#flexdirection) |设置布局的主轴方向。<br/>默认值：FlexDirection.Column|
-
-layoutDirection优先级高于rowsTemplate和columnsTemplate。根据layoutDirection设置情况，分为以下三种设置模式:
-
-- layoutDirection设置纵向布局（FlexDirection.Column 或 FlexDirection.ColumnReverse）
-
-	此时columnsTemplate有效（如果未设置，取默认值）。例如columnsTemplate设置为"1fr 1fr"、rowsTemplate设置为"1fr 1fr 1fr"时，瀑布流组件纵向布局，辅轴均分成横向2列。
-
-- layoutDirection设置横向布局（FlexDirection.Row 或 FlexDirection.RowReverse）
-
-	此时rowsTemplate有效（如果未设置，取默认值）。例如columnsTemplate设置为"1fr 1fr"、rowsTemplate设置为"1fr 1fr 1fr"时，瀑布流组件横向布局，辅轴均分成纵向3列。
-
-- layoutDirection未设置布局方向
-
-	布局方向为layoutDirection的默认值：FlexDirection.Column，此时columnsTemplate有效。例如columnsTemplate设置为"1fr 1fr"、rowsTemplate设置为"1fr 1fr 1fr"时，瀑布流组件纵向布局，辅轴均分成横向2列。
-
-## 事件
-
-
-除支持[通用事件](ts-universal-events-click.md)外，还支持以下事件：
-
-
-| 名称 | 功能描述 |
-| -------- | -------- |
-| onReachStart(event: () => void) | 瀑布流组件到达起始位置时触发。 |
-| onReachEnd(event: () => void)   | 瀑布流组件到底末尾位置时触发。 |
-
-
-## auto-fill说明
-
-WaterFlow的columnsTemplate、rowsTemplate属性的auto-fill仅支持以下格式：
-
-```css
-repeat(auto-fill, track-size)
-```
-
-其中repeat、auto-fill为关键字。track-size为行高或者列宽，支持的单位包括px、vp、%或有效数字，track-size至少包括一个有效行高或者列宽。
