Trigger suggest after typing a character, for part of a text or search field

Is it possible to build a control like Twitter’s edit box, that autocompletes hashtags after the # character is typed, and leaves the rest of the text intact?

.

Webix does this in the Comments widget when @-mentioning users, but I need only the edit box.

tag input triggered by one character

I’ve looked at related threads but they deal with the entire text box.

Thanks!

That’s an interesting suggestion, thanks for the idea.

We will add it to our backlog and consider extracting a Comments input area into a standalone widget, but now I cannot tell you the final decision or estimate.
