Specifying Accepted File Types
This will tell the file chooser to default to showing only images and will
get forwarded to a hidden <input type="file"> in the shadow root.
HTML
<rhino-editor accept="image/*"></rhino-editor>
Caution
Users can still override the behavior and upload any file. It is recommended to sanitize files on your server, and also read the section below of preventing file uploads.
Preventing Uploads
JavaScript
function pngOnly (event) {
if (event.file.type !== 'image/png') {
event.preventDefault()
}
}
document.querySelector("#png-only").addEventListener('rhino-file-accept', pngOnly)
HTML
<rhino-editor id="png-only"></rhino-editor>
