Glyphicons no longer supported in Bootstrap 4

Question

I've read, from official docs, that Glyphicons were dropped from Bootstrap 4.

Today, in my searching for implementing checbox button, I've found one snippet that I appreciate very much:

Snippet for Checkbox 3.0

The problem is that this version is for Bootstrap 3.0, where Glyph were supported yet.

So I've 2 question:

1. Wich is a good alternative to Glyphicons? Or there is a way to use them yet?
2. How I may change the html and js snippet above to make it working wuth Bootstrap 4?

Answer 1

1 - Wich is a good alternative to Glyphicons? Or there is a way to use them yet?

The best alternative IMHO: http://fontawesome.io/icons/

2 - How I may change the html and js snippet above to make it working wuth Bootstrap 4?

jQuery Checkbox Buttons - Bootstrap 4

You need to change the JS:

settings = {
    on: {
        icon: 'fa fa-square-o'
    },
    off: {
        icon: 'fa fa-check-square-o'
    }
};

And the css class .hidden is now deprecated so Bootstrap recommends to use style="display: none" instead.
