Multi selection textbox using only angularjs

Decades ago, the common style for text editors have been established; it dates back to old CUA specs. In this style, all text editors and world processors became the tools where only a single range in the text flow can be selected. It's nearly impossible to find something different these days. I used to like multiselection text editors, but probably they are considered as too confusing to most users.

The situation is much more difficult for JavaScript embedded in a browser. In your own UI application, you can do whatever you want (no matter is the user like it or not), but JavaScript will only play by the rules of the browser.
