# Page Explorer Pages are the individual views or screens that organize your application's functionality. Heisenware uses a hierarchy of pages and sub-pages to keep your app structured and easy to navigate. ## Managing your app structure You can manage the structure of your app via the pages panel. Click on the navigator icon () on the left panel to open it. ### Page types * **Pages**: These are your top-level screens. By default, they are automatically added to the app’s main navigation menu. * **Subpages**: These are nested under a main page. They do not show up in the main navigation menu automatically. They are typically used for detail views, settings, or pop-up style content that you want to link to manually.

### Creating, deleting, and organizing pages * **Add/Duplicate**: Right-click any page in the panel to create a new page, a subpage, or to duplicate an existing page to save time. * **Delete**: Right-click any page in the panel and click delete. Note that the first page in your app cannot be deleted.

* **Change order**: To change the order of pages and how they appear in the app's main menu, refer to the [navigation settings](#main-navigation-menu). {% hint style="info" %} If you need more vertical space, refer to page height settings as part of the [UI Builder toolbar](/app-builder/build-frontend.md#the-toolbar). {% endhint %} ## In-app navigation The app has a navigation menu that users can click. However, page switches can also be triggered by logic and clicks on widgets. By default, apps just have bottom tabs.

### Main navigation menu This is the standard menu that appears across all pages and subpages. * **Configuration**: Click the navigator icon () in the top bar to open the settings. * **Menu types**: You can choose between: * **None**: No navigation menu. * **Bottom tabs**: (Default) A fixed tab bar at the bottom of the screen. * **Menu drawer**: A classic "burger" menu. You can set its position (top or left) and its behavior (push or overlap). * **Top bar**: Displays only the `App Bar Title` at the top with no menu icons. * **Top bar and bottom tabs**: Combines both for a standard mobile app feel. * **The "App Bar" behavior**: Subpages automatically inherit the same `App Bar Title` as their parent page, ensuring the user knows which section they are currently in. * **Customization**: In the settings, you can hide specific pages from the menu, edit their display labels, or assign them unique icons. * **Page order**: Use the arrow icons () in the routes menu to reorder pages and define how they appear in the navigation.

### Widget links You can turn any [button](/app-builder/build-frontend/widgets/trigger-widgets/button.md) or [icon](/app-builder/build-frontend/text-icons-and-images.md) into a page switch trigger. * **How to link**: Simply drag a page from the pages panel and drop it directly onto a button or icon on your UI canvas. * **Use case**: This is the primary way to let users open subpages (e.g., clicking a "Machine Details" button to open that specific detail view) or navigate in apps without a main menu. ### Logic-driven navigation Page switching can also be triggered automatically by your backend logic. * **How to link**: Drag a page from the pages panel onto a function's output. * **Use case**: If a function detects an error or a successful form submission, the backend can "push" the user to an error or success page automatically. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
