# `useRowSelect`
- Plugin Hook
- Optional
`useRowSelect` is the hook that implements **basic row selection**. For more information on row selection, see Row Selection
### Table Options
The following options are supported via the main options object passed to `useTable(options)`
- `state.selectedRowPaths: Set<RowPathKey>`
- Optional
- Defaults to `new Set()`
- If a row's path key (eg. a row path of `[1, 3, 2]` would have a path key of `1.3.2`) is found in this array, it will have a selected state.
- `initialState.selectedRowPaths`
- Identical to the `state.selectedRowPaths` option above
- `manualRowSelectedKey: String`
- Optional
- Defaults to `isSelected`
- If this key is found on the **original** data row, and it is true, this row will be manually selected
- `getResetSelectedRowPathsDeps: Function(instance) => [...useEffectDependencies]`
- Optional
- Defaults to resetting the `expanded` state to `[]` when the dependencies below change
- ```js
const getResetSelectedRowPathsDeps = ({ rows }) => [rows]
```
- If set, the dependencies returned from this function will be used to determine when the effect to reset the `selectedRowPaths` state is fired.
- To disable, set to `false`
- For more information see the FAQ ["How do I stop my table state from automatically resetting when my data changes?"](./faq#how-do-i-stop-my-table-state-from-automatically-resetting-when-my-data-changes)
### Instance Properties
The following values are provided to the table `instance`:
- `toggleRowSelected: Function(rowPath: String, ?set: Bool) => void`
- Use this function to toggle a row's selected state.
- Optionally pass `true` or `false` to set it to that state
- `toggleRowSelectedAll: Function(?set: Bool) => void`
- Use this function to toggle all rows as select or not
- Optionally pass `true` or `false` to set all rows to that state
- `getToggleAllRowsSelectedProps: Function(props) => props`
- Use this function to get the props needed for a **select all checkbox**.
- Props:
- `onChange: Function()`
- `style.cursor: 'pointer'`
- `checked: Bool`
- `title: 'Toggle All Rows Selected'`
- `isAllRowsSelected: Bool`
- Will be `true` if all rows are selected.
- If at least one row is not selected, will be `false`
- `selectedFlatRows: Array<Row>`
- The flat array of rows that are currently selected
### Row Properties
The following additional properties are available on every **prepared** `row` object returned by the table instance.
- `isSelected: Bool`
- Will be `true` if the row is currently selected
- `toggleRowSelected: Function(?set)`
- Use this function to toggle this row's selected state.
- Optionally pass `true` or `false` to set it to that state
