3.8.0 View Mode and Edit Mode
Like the book list, the section list is operated by switching between View mode and Edit mode.
View mode
Right after opening the section list, you are in View mode. The top right shows:
- Edit: Switch to Edit mode
- Reorder: Open the reorder dialog (see 3.8.4 Reordering Sections)
- Sort: Configure column sorting
- Grid view / List view: Toggle the appearance of the list

Edit mode
Clicking the Edit button switches to Edit mode, and the toolbar changes to:
- Remove: Bulk-remove the selected sections
- Done: Return to View mode
A checkbox appears at the start of each section row. Selecting at least one enables Remove and shows N selected at the top.

3.8.1 Creating Sections
To create a new section, click the Add button (+) at the bottom-right of the screen. A menu appears letting you choose the kind of section to add.

Menu Options
| Option | Corresponding section type |
|---|---|
| Add Photo/Movie | Creates a Photo Section or Movie Section from image files (JPEG, PNG, GIF, WebP, etc.) or video files (MP4, MOV, etc.) |
| Add File | Creates a PDF Section or Multi-file Section from PDF, Office documents, text, or other files |
| Add Website | Creates a Website Section from a given URL |
Note: Choosing Add Photo/Movie or Add File opens a file picker. Selecting a single file creates a single-typed section (Photo / Movie / PDF) matching the file's format; selecting multiple files creates a Multi-file Section that groups them into one section.
Creating a Photo Section
A Photo Section is created from a single image file.
- From the add-section menu, click Add Photo/Movie
- In the file picker, select exactly one image file (JPEG, PNG, GIF, WebP, etc.)
- When the upload completes, the section is created
- Edit the section name or description if needed, then click Save
Note: If you select two or more image files, they are grouped together as a Multi-file Section (see below) instead of separate Photo Sections.
Creating a Movie Section
A Movie Section is created from a single video file.
- From the add-section menu, click Add Photo/Movie
- In the file picker, select exactly one video file (MP4, MOV, etc.)
- When the upload completes, the section is created
- Edit the section name or description if needed, then click Save
Creating a Website Section
- From the add-section menu, click Add Website
- The New Web Section dialog appears
- Enter the following information:
| Item | Required | Description |
|---|---|---|
| Title | ○ | Name of the section |
| URL | ○ | URL of the web page |
| Description | - | Description of the section |
- Click the Save button

Tip: Website sections are convenient for linking to internal portals or external services.
Creating a PDF Section
A PDF Section is created from a single PDF file, or a single document file that is automatically converted to PDF.
- From the add-section menu, click Add File
- In the file picker, select exactly one PDF file (or a Word / Excel / PowerPoint file, which is auto-converted to PDF on the server)
- When the upload completes, the section is created (Office files are converted on the server before the section becomes viewable)
- Edit the section name or description if needed, then click Save
Note: If you select two or more files, they are grouped together as a Multi-file Section (see below) instead of separate PDF Sections.
Creating a Multi-file Section
A Multi-file Section groups multiple files and/or web pages into one section. The files can be of mixed types.
- From the add-section menu, click either Add Photo/Movie or Add File (a multi-file section can be created from either file picker)
- In the file picker, select two or more files at once
- The Edit Section dialog opens with the selected files listed as its content
- Enter the following information:
| Item | Required | Description |
|---|---|---|
| Title | ○ | Name of the section |
| Description | - | Description of the section |
- Optionally add more content:
- Files: Click the Add button to add more files
- Web pages: Click the Add Web button and enter a title and URL
- Edit the Title of each content item as needed
- Remove unwanted content using the Delete button (
)
- Click the Save button
Tip: Even when all files are of the same type (all images, all PDFs, etc.), selecting two or more in the file picker creates a Multi-file Section. This is useful for managing related documents (PDFs, images, videos) and web pages together.
Note: You cannot create a Multi-file Section that consists solely of web pages from scratch. First create the section by selecting two or more files, then follow 3.8.3 Editing and Removing Sections to remove the placeholder files and add web pages.
