# Page-by-Page Form Editing (Angular)

With Survey Creator, users can build surveys that contain thousands of questions spread across hundreds of pages. To make navigation within lengthy surveys easier, you can enable page-by-page edit mode. In this mode, the design surface displays only one survey page at a time, allowing survey authors to focus on the page they configure at the moment. Users can quickly jump from one survey page to another using the page navigator instead of scrolling through the entire survey. To enable page-by-page edit mode, set the [`pageEditMode`](https://surveyjs.io/survey-creator/documentation/api-reference/icreatoroptions#pageEditMode) property to `"bypage"`.
