i want to develop a plugin that has a panel contains many icons, click each icon will show something popup.
and the panel should stick with the property panel, like this. can you give me some advices, how to do this.
See some older threads
It's a pretty custom thing to try and do and there is no established easy route. It's likely to break if Sketch makes changes.
The feature of custom panels for plugins used to be on the plugin roadmap (when it was public) but I'm not sure what the status of it is now.
robin thks, that's really helpful.
