# ui:useProps **Reference:** [View Source](https://github.com/jramke/fluid-primitives/tree/main/Classes/ViewHelpers/UsePropsViewHelper.php) Use props from another component. This ViewHelper allows you to import all props from another component and register them for the current component. This is helpful/needed when consuming the `primitives` components or when you want to reuse props from another component. You can also override default values of the imported props by passing a `defaults` array with key-value pairs. ## Examples `Tooltip/Root.html` that uses the tooltip primitive: ```html ``` If you dont want all props from a component, you can also selectively import props by passing an array of prop names to the `props` argument. ```html // ... ``` ## Limitation Currently its not possible to use this `useProps` and `spreadProps` pattern with required arguments because of how Fluid parses the templates. If a prop for a primitive is required, we use the `requiredAtRuntime` argument on the [ui:prop](./prop) ViewHelper. ## Arguments | Name | Type | Description | Required | Default | |------|------|-------------|----------|--------| | `name` | string | Name of component to use the props from | Yes | - | | `defaults` | array | Default values for props to override the imported ones. Key-value pairs | No | [] | | `props` | array | Only use a subset of props from the referenced component. Value should be an array of prop names. | No | [] |
