File Attachments in Vue RichTextEditor component

The Rich Text Editor allows you to attach a file based on the file upload. You can attach your files using the file upload or drag-and-drop from your local path. When the file upload gets success, the attachment link inserts into the content.

In the below sample, configure the saveUrl and path properties to achieve file attachments.

    1. saveUrl: Provides service URL to save the files.
    2. path: Specifies the location to store the image.

The following sample illustrates how to attach a file in the Rich Text Editor.
