How to override options of Gutenberg core components?

[geertvansoest]

Hi there,

I just found out Gutenberg and I think it's amazing. Despite that, I'm challenging some issues at implementing it in a WordPress website I'm currently developing.

At this website, I want to use some core components, and also create some custom components. I want to restrict the core components a bit, for example our client should not be able to customize the font sizes at the paragraph component. And at the columns component, he should be able to only add max. 3 columns (the max. is 6 by default).

For now, I did some attempts for disabling / removing the font size block at the paragraphs component.

• I did experimenting a lot using the API's as shown on https://wordpress.org/gutenberg/handbook/extensibility/extending-blocks.
• I did some testing with the solution as is given in Remove a panel from the settings? #6225, which looks a lot like the API editor.BlockEdit (https://wordpress.org/gutenberg/handbook/extensibility/extending-blocks/#editor-blockedit). But I didn't found out how I can remove some elements. Seems like the BlockEdit API only can add new one.
• Someone else tried also tried to remove the font size block using an theme support hook (Error when interacting with a paragraph block #10972), but that won't work too.

The main question is; is it possible to override the attributes/edit form for core components anyhow?

Thanks in advance!

Kind regard,
Geert

I tried researching this and found #12861 which seems to imply that what you are asking cannot be solved without first adding a filter.

I also found #6023 and I think your questions are similar enough that I would like to close this issue and consolidate to #6023.
