Are there any custom tutorials related to buttons?

I need to add a checkbox before the plus icon, and trigger its display and selection through Custom Items in the Slash Menu. This way, I can precisely select which contents need to be exported, quoted, set to read-only in real-time collaboration mode, and passed on to some AI models for further functions.

@jerrycompal this is possible by customizing the blockSideMenuFactory. The default React implementation is here:

BlockNote/packages/react/src/hooks/useBlockNote.ts

Line 70 in 496e20b

blockSideMenuFactory: createReactBlockSideMenuFactory(

This is a bit advanced, there is no documentation related to this yet. I'll keep this issue open and would be great to hear if customizing this way works for your scenario

Docs are now available for customizing both the side menu and slash menu, should hopefully be what you're looking for:
