Just starting off with my first umbraco project, in another CMS I am familiar with, I was able to create a content type and use that within another content type. Is there a possibility to do that in umbraco? I have created a "Button" document type, it has fields "URL", "Text" and "Label" I have another document type called section content. Am i able to add the document type "Button" as a property in section content? This way whenever a document type needs a button its streamlined with the same characteristics as other document types.

If you want to make reusable elements (could be a button, but i'd do that an other way), i'd definitly check out the Block list editor: https://docs.umbraco.com/umbraco-cms/fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/block-editor/block-list-editor

Awesome ill switch that around then! make them from document types into block lists! Seems like thats the way to go thank you @Ambert !!
