Uses optional [(ngModel)] directive to bind file. (if [(ngModel]) exists, [fileSelect] is omitted)

Example for usage:

<input type="file" tdFileSelect [(ngModel)]="files" multiple>

API Summary

Properties:

Name	Type	Description
multiple	boolean	Sets whether multiple files can be selected at once in host element, or just a single file. Can also be "multiple" native attribute.
fileSelect	function($event)	Event emitted when a file or files are selected in host [HTMLInputElement]. Emits a [FileList or File] object. Alternative to not use [(ngModel)].

tdFileDrop

Usage

Add the directive wherever you want to add drop support to an element to bind a [File | FileList] into a class model.

To add effect when ongragenter event is executed, override .drop-zone class in the context you are using it.

Note: if element has child elements, add * { pointer-events: none; } to avoid event being thrown again while navigating in child elements.

Example for usage:

<div tdFileDrop (fileDrop)="files = $event" multiple [disabled]="disabled">
</div>
