[Feature]: Mention Component

[BayBreezy]

Describe the feature

Someone asked me about a feature request. I am not skilled enough to do this type of thing so I am asking you guys for help, please.

Hello! Do you implementing feature requests? If yes I'd appreciate to see something similar to https://www.naiveui.com/en-US/os-theme/components/mention (https://codesandbox.io/s/rfn2nx)

My scenario of usage:

If mention was triggered by : symbol, then show one list of items.
If mention was triggered by @ symbol, then show another list of items.
It should support textarea.
It should support customizable render of list item.
It should optionally support virtual list render? In case there is to much items.
If that's already possible in any way, i'll appreciate any help.
