Flow-btn and multiple files

[Fabiencdp]

Hi !

I can't select multiple files with the flow-btn directive, is that normal ?
Here is a way to do that ?

Here is a bit of code :

`

<div flow-init
		 flow-files-added="vm.upload( $files )"
		 flow-drag-enter="style={border:'4px dashed #8CC746'}" flow-drag-leave="style={}" ng-style="style" class="input--file-wrapper">

	<div class="dropzone" flow-drop>

		<div class="input--file-content">

                            <!-- some stuff to handle images previews -->   

			<div class="input--file-content--button" flow-btn multiple>Choisir un fichier</div>

		</div>

	</div>

</div>
