Can you clarify where this code lives/where are you using an html editor? I’m not seeing this in your Builder space. Is this content you are authoring in Builder? Any content links or code you can share would be great!
To confirm, are you referring to writing code blocks like the code blocks within the content field on the entry you shared above? If you’re wanting to display code in a text block, you can either edit the text as code and add tags to create code blocks or you can highlight the text and select the code icon to convert the text to code. Both options will wrap the text in an html code tag. Another route you could take would be to create a custom component specifically for code blocks similar to the example here.
