Each block determines which controls appear by default in the settings sidebar. For a paragraph block, you’ll always see text and background color options because the block declares these as defaults.
You can reveal additional controls by clicking the three dots menu, but you can’t remove the defaults that each block wants to show. Once you click away from a block, any additional controls you’ve revealed will reset back to the default view.
This behavior ensures a consistent experience – blocks always show their most important settings while keeping the interface clean. When you return to edit a block, you’ll see the core controls immediately and can access advanced options when needed.
Understanding this pattern helps you work more efficiently in the site editor and better plan your block theme’s user experience.
