{{< callout info >}}
The recommended plugin to animate custom file input: [bs-custom-file-input](https://www.npmjs.com/package/bs-custom-file-input), that's what we are using currently here in our docs.
{{< /callout >}}
The file input is the most gnarly of the bunch and requires additional JavaScript if you'd like to hook them up with functional *Choose file...* and selected file name text.
{{< example >}}
<div class="form-file">
<input type="file" class="form-file-input" id="customFile">
<label class="form-file-label" for="customFile">
<span class="form-file-text">Choose file...</span>
<span class="form-file-button">Browse</span>
</label>
</div>
{{< /example >}}
Add the `disabled` attribute to the `<input>` and the custom markup will be updated to appear disabled.
{{< example >}}
<div class="form-file">
<input type="file" class="form-file-input" id="customFileDisabled" disabled>
<label class="form-file-label" for="customFileDisabled">
<span class="form-file-text">Choose file...</span>
<span class="form-file-button">Browse</span>
</label>
</div>
{{< /example >}}
Longer placeholder text is truncated and an ellipsis is added when there's not enough space.
{{< example >}}
<div class="form-file">
<input type="file" class="form-file-input" id="customFileLong">
<label class="form-file-label" for="customFileLong">
<span class="form-file-text">Lorem ipsum posuere consectetur est at lobortis nulla vitae elit libero a pharetra augue fusce dapibus tellus ac cursus commodo tortor mauris condimentum nibh ut fermentum massa justo sit amet risus cras mattis consectetur purus sit amet fermentum</span>
<span class="form-file-button">Browse</span>
</label>
</div>
{{< /example >}}
We hide the default file `<input>` via `opacity` and instead style the `<label>`, and declare a `width` and `height` on the `<input>` for proper spacing for surrounding content.
