[Modules] Add user prompt

Feature Request

Since Fomantic UI presents not only UI but some interactive modules it would be great to add a user prompt module.

The module should ask user for some decision like “File 1.txt already exists. Would you like to overwrite this file?” And also can be invoked from js with text, label and buttons (actions) with callbacks.

Example

From one hand poor prompt is already can be constructed via toast actions but it displays only toast but prompt (no dimmer, no visual highlights). From another hand prompt can be displayed via modal but with no dynamic content, actions and callbacks. So I suggest to merge modal UI with toast actions.

Example

Run confirm('Implement this?') in browser console to see default implementation.

In my mind, what you have in your example is easier (and quicker) than adding a whole new module/feature that will bloat the underlining Fomantic JS to do essentially the same thing but with a different name

If something, on the other hand, can be made easier where logic is needed to do various calculations, take into account other various things to stitch different aspects together, then that would be cool (like my Sidebar idea https://github.com/fomantic/Fomantic-UI/issues/1243)

Perhaps some kind of widget/extension factory/thingamajig could be useful to define/repurpose what you’re looking for 🤔
