"Angular File Upload Made Easy with Drag-and-Drop Functionality and Cleverly Positioned

Encountering an issue with Angular File upload in conjunction with relatively positioned elements. The drop target is set to 100% width and height, absolutely positioned. While dragging a file over any non-relatively positioned element, the overlay functions as expected. However, when dragged over a relatively positioned element, the drag event is not registered due to these elements appearing on top of the dropArea.

Attempting to resolve this by applying a z-index to the drop target yields successful drag and drop functionality; however, it results in the inability to click anything on the user interface.

Outlined below is my approach:

HTML

<html>
  <head>...</head>
  <body>
    <div id="dropArea">...</div>
    <div id="siteContent">
      <div class="row">
        <!-- Dragging onto this relatively positioned element fails -->
        <div class="col-md-12">...</div> 
        <div>...</div>
      </div>
    </div>
  </body>
</html>

CSS

#dropArea {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
}

Is there a way to assign a z-index to the dropArea while still permitting clicks to pass through?

Answer №1

To solve this issue, I enclosed the entire webpage content within a designated drop area.

<html>
<head>...</head>
<body>

<div id="dragArea" class="dragArea" ng-file-drop="onFileSelect($files)" ng-file-drag-over-class="fileAdded">
  <div id="drag-content-container">
    <div id="drag-content">
      <img src="img/app/files-upload-dd.png">
      <h1>Drop Files Here!</h1>
    </div>
  </div;

  <div class="content-page">...</div>
</div>

</body>
</html>
