React - input type file Semantic UI React

Question

I'm trying to implement a file upload, but using SUIR <Input>, button, label, etc.

This is strictly about the use of the elements in render.

Using regular html <label> and <input> elements this process works as expected.

  <Form.Field>
    <label>File input & upload for dataschemas & datasources</label>
    <input type="file" onChange={this.fileChange} />
    <Button type="submit">Upload</Button>
  </Form.Field>

Now I'm trying to use SUIR <Input> element, as well as some props with the <Button> element for styling.

  <Form.Field>
    <label>File input & upload </label>
    <Input type="file" onChange={this.fileChange}>
      <Button
        content="Choose File"
        labelPosition="left"
        icon="file"
      />
    </Input>
    <Button type="submit">Upload</Button>
  </Form.Field>

You can visit the codesandbox here to get a better visual idea of what I'm talking about.

When I click Choose File in the SUIR implementation example it does not prompt the user to chose a file from their system, whereas the regular html <input> does. I'm not sure how to get <Input type="file ...> in semantic to behave the same way.

SUIR doesn't provide a FileInput button solution out of the box. But you can easily create your own implementation of such button. For instance, usually this is done by using a hidden file input and a button which triggers the hidden input click when user clicks on it:

  <Button
    content="Choose File"
    labelPosition="left"
    icon="file"
    onClick={() => this.fileInputRef.current.click()}
  />
  <input
    ref={this.fileInputRef}
    type="file"
    hidden
    onChange={this.fileChange}
  />

Where this.fileInputRef is a React ref created by React.createRef() method. You can check this codesandbox example with the above solution.
