Do placeholders in topics show when I publish?

No, the placeholder buttons and the associated text don't show when published. They're a part the topic editor interface that offers guidance and provides quick access to common elements. Think of placeholders as reminders for elements that are typically used in a given topic type.

It's common for easyDITA customers to specify their own set of buttons and configurations to meet their specific authoring needs. easyDITA is highly configurable, so just let us know if you want different placeholder text and buttons.
