Usage#

import { FileUpload } from 'primereact/fileupload';

<FileUpload.Root>
    <FileUpload.Content>
        <FileUpload.ItemGroup>
            <FileUpload.Item>
                <FileUpload.ItemPreview />
                <FileUpload.ItemInfo>
                    <FileUpload.ItemName />
                    <FileUpload.ItemSize />
                </FileUpload.ItemInfo>
                <FileUpload.Remove></FileUpload.Remove>
            </FileUpload.Item>
        </FileUpload.ItemGroup>
    </FileUpload.Content>
</FileUpload.Root>

Behavior#

Polymorphic Rendering#

Use as on any sub-component to change the rendered HTML element.

<FileUpload.Root as="section">
    <FileUpload.Content as="main"></FileUpload.Content>
</FileUpload.Root>

Default elements: Root=div, Content=div, List=div, ItemGroup=div, Item=div, ItemPreview=img, ItemInfo=div, ItemName=div, ItemSize=div, Remove=button.

Render Function Children#

Root accepts a render function as children, providing access to the component instance with state, methods, and computed properties.

<FileUpload.Root>
    {(instance) => (
        <>
            <button onClick={instance.choose}>Choose Files</button>
            <button onClick={instance.upload}>Upload</button>
            <FileUpload.Content>
                <FileUpload.ItemGroup>
                    {instance.state.files.map((file, index) => (
                        <FileUpload.Item key={file.name + file.size} file={file} index={index}>
                            <FileUpload.ItemPreview />
                            <FileUpload.ItemInfo>
                                <FileUpload.ItemName />
                                <FileUpload.ItemSize />
                            </FileUpload.ItemInfo>
                            <FileUpload.Remove onClick={() => instance.remove(index)}>Remove</FileUpload.Remove>
                        </FileUpload.Item>
                    ))}
                </FileUpload.ItemGroup>
            </FileUpload.Content>
        </>
