I'm using Drupal 8, including paragraphs.
I have a content type with a paragraph field, and this paragraph contains a fieldgroup of two fields that display in horizontal tabs.
When adding content, on save only the content in the active tab should be set to display on the page. In other words, you choose one tab or the other, add content into its designated field and save. The content in that active tab is the content that will display when viewing the page (even if there is content in the other tab).
How can I display the content from only the tab that was active on save?
