The dropdown and tooltips look useful, but FYI it's really simple to make a file picker. Just put a hidden input type="file" on the page, then:

    document.getElementById("that-element").addEventListener("change", function(e) {
        // e.target.files
    });
    document.getElementById("that-element").click();

It's not so easy

    document.getElementById("that-element").click();

doesn't exist. You need to use something like

        /** Creates the click on the input */
        const clickEvent = document.createEvent( "MouseEvents" );
        clickEvent.initEvent( "click", true, false );
        document.getElementById("that-element").dispatchEvent( clickEvent );

Here's code I wrote a while ago that did exactly what I specified and worked in production on all major browsers:

Here's the code in the jQuery library you linked to that does exactly this as well:

It has some problems with input type=file elements.

The devil is in the details, although obviously your code works for any other clickable elements.
