The Page Setup group has two adjacent tools used together. Page Settings defines the exported canvas size (width x height) of each page; it is the basis for layout, so fix it before arranging shapes or binding behaviors. Page Breadcrumb defines, for each page, whether it appears in the host's top breadcrumb, at which level, and under what name. In short: Page Settings controls only the canvas size, Page Breadcrumb controls only navigation display, and neither configures alarm scope here.
Feature
Feature: Page Settings & Page Breadcrumb
Use Page Settings to set each page's exported canvas size (a preset or a custom width/height), and Page Breadcrumb to set that page's level and display name in the host's breadcrumb. Both live in the Page Setup group on the ribbon.
What it is and what it's for
The Page Setup group has two adjacent tools used together. Page Settings defines the exported canvas size (width x height) of each page; it is the basis for layout, so fix it before arranging shapes or binding behaviors. Page Breadcrumb defines, for each page, whether it appears in the host's top breadcrumb, at which level, and under what name. In short: Page Settings controls only the canvas size, Page Breadcrumb controls only navigation display, and neither configures alarm scope here.
How to use it: Page Settings fields
Open the Page Settings dialog, fill three fields, click OK. It applies to the current page only:
Size: size-preset dropdown with 960 x 540, 1008 x 720, 864 x 612, 720 x 540, 1280 x 720, 1920 x 1080, Custom
Width / Height: dimensions in pixels. Picking a preset auto-fills both; choose Custom to type your own
Validation: width and height must each be a number greater than 0, or the save is rejected
After you change the size, the current page's export file name is cleared, so the next Export HTML regenerates the file name from the page state
How to use it: Page Breadcrumb fields
Page Breadcrumb is a grid, one row per page, edited inline. Edit the cells and click Save:
Page Name: syncs with the PowerPoint outline title and also determines the exported file name; cannot be empty (the default title placeholder is ignored on export)
Level: breadcrumb level, must be a non-negative integer. 0 = not in the breadcrumb (hidden); 1 = the entry/main page after a second-level menu; 2 and above = a child page inside the same screen package
Breadcrumb Display Name: the name shown for this page in the host breadcrumb; falls back to Page Name when left blank
Level restarts from 1 inside each second-level-menu package; it is not a site-wide level. Pages on the same tier share the same number
Example:
Page Name = cc01
Level = 1
Breadcrumb Display Name = PIY1C1
-> Host shows: L1 menu > L2 menu > PIY1C1
When to use it
When you start a new page, fix the target size in Page Settings first (e.g. 1920 x 1080 for a full-screen main view, 1008 x 720 for a view with a side popup), then do layout, behaviors, and navigation. Once the page-to-page jumps are settled, use Page Breadcrumb to tag each page: give the main view a second-level menu lands on Level 1, give a device-detail child page opened from it Level 2, and set pure-popup pages that should not stand alone in the navigation to Level 0 so they stay hidden.
Boundaries and common mistakes
A few easy traps:
Page Breadcrumb covers only navigation level and name, not alarm scope. The breadcrumb node's alarm/fault state and the page's right-side alarm window both come from PageJson.alarm (maintained in script, do not configure it twice)
Do not treat Level as a global level; it is relative within the second-level-menu package and restarts at 1 in each package
The host infers parent/child from export order plus level: the nearest preceding page with a lower Level becomes the parent, so keep the exported page order stable
Changing navigation structure (level, display name, adding/deleting/renaming pages) is a whole-package change and requires a full Export HTML, not a current-page-only export

Pick a size preset or a custom width/height to set the exported canvas size of the current page.
Figure 2: Page Breadcrumb
Set each page's breadcrumb level and display name to control how it appears in the host navigation.
