How to make sidebar instead of popup in chrome extension?

Question

Google Chrome

Hello!
I'm trying to make an extension for Chrome and the question arose
Is it possible to make it so that when you click on the extension icon, a panel extends to the right (like a menu on sites).
now it is a popup window ("default_popup": "popup.html")
The extension is simple, consisting of several buttons: select such and such an html tag (checkbox button), get the contents of the tag and follow the link ('site.ru?url='+ location.href).

Answer 1

it is impossible in google chrome, this can be done in opera, for example, because they made their own api.
