The **<Grid>** component is a two-dimensional layout. The component is divided into rows and columns, to form cells. You can specify the cell where an item is located and combine different grids to form various layouts.
## Required Permissions
None
## Child Components
This component contains the child component [\<GridItem>](ts-container-griditem.md).
## APIs
Grid()
## Attributes
| Name | Type | Default Value | Description |
| -------- | -------- | -------- | -------- |
| columnsTemplate | string | '1fr' | Number of columns in the current grid layout. If this parameter is not set, one column is used by default. For example, '1fr 1fr 2fr' divides the component into three columns, with four equal parts. The first column occupies one part, the second column occupies one part, and the third column occupies two parts. |
| rowsTemplate | string | '1fr' | Number of rows in the current grid layout. If this parameter is not set, one row is used by default. For example, '1fr 1fr 2fr' divides the component into three rows. The width allowed by the parent component is divided into four equal parts. The first row occupies one part, the second row occupies one part, and the third row occupies two parts. |
| editMode<sup>8+</sup> | boolean | false | Whether to enter editing mode. In editing mode, you can drag the **<[GridItem](ts-container-griditem.md)>** in the **<Gird>** component. |
| layoutDirection<sup>8+</sup> | [LayoutDirection](ts-appendix-enums.md#layoutdirection-enums) | LayoutDirection.Row | Main axis direction of the layout. The options are as follows:- **LayoutDirection.Row**: Horizontal layout, where the child components are arranged in the same direction as the main axis runs along the rows.- **LayoutDirection.Column**: Vertical layout, where the child components are arranged in the same direction as the main axis runs down the columns. |
| maxCount<sup>8+</sup> | number | 1 | Maximum number of rows that can be displayed. |

The **<List>** component provides a list container that presents a series of list items arranged in a column with the same width. It supports presentations of the same type of data in a multiple and coherent row style, for example, images or text.
## Required Permissions
None
## Child Components
This component contains the child component [\<ListItem>](ts-container-listitem.md).
| space | number | No | 0 | Spacing between list items. |
| initialIndex | number | No | 0 | Item displayed at the beginning of the component when the current list is loaded for the first time, that is, the first item to be displayed.

By default, there is no divider.<br/>**strokeWidth**: stroke width of the divider.<br/>**color**: color of the divider.<br/>**startMargin**: distance between the divider and the start of the list.<br/>**endMargin**: distance between the divider and the end of the list. |
| editMode | boolean | false | Whether the **<List>** component is in editable mode. |
| edgeEffect | EdgeEffect | EdgeEffect.Spring | Sliding effect. For details, see EdgeEffect enums. |
| chainAnimation | boolean | false | Whether to display chained animations on this list when it slides or its top and bottom are dragged. The list items are separated with even space, and one item animation starts after the previous animation during basic sliding interactions. The chained animation effect is similar with spring physics.<br/>- **false**: No chained animations are displayed.<br/>- **true**: Chained animations are displayed. |
| multiSelectable<sup>8+</sup> | boolean | false | Whether to enable mouse frame selection.<br/>- **false**: The mouse frame selection is disabled.<br/>- **true**: The mouse frame selection is disabled. |
