Include an extern fileinput component

I want to use this component in Boostrap studio :

Ho to do ?
Thank you

You could download the needed js and css files and import them into the apropriate folders of your project. For initialization add an extra js file named e.g. onload.js with

document.addEventListener("DOMContentLoaded", function(event) {
// your init code here

that’s all on the client side.
Note, that for receiving data / uploads you need active code on the server like php or similar.
