Display Items

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
• Edit: Edit the selected section (enabled only when exactly one is selected)
• Export: Export the files in the selected sections (see 3.8.6 Exporting Section Files)
• 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. In grid view the checkbox appears at the top right of the section card's title area.

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

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.

1. From the add-section menu, click Add Photo/Movie
2. In the file picker, select exactly one image file (JPEG, PNG, GIF, WebP, etc.)
3. When the upload completes, the section is created
4. 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.

1. From the add-section menu, click Add Photo/Movie
2. In the file picker, select exactly one video file (MP4, MOV, etc.)
3. When the upload completes, the section is created
4. Edit the section name or description if needed, then click Save

Creating a Website Section

1. From the add-section menu, click Add Website
2. The New Web Section dialog appears
3. Enter the following information:

1. 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.

1. From the add-section menu, click Add File
2. In the file picker, select exactly one PDF file (or a Word / Excel / PowerPoint file, which is auto-converted to PDF on the server)
3. When the upload completes, the section is created (Office files are converted on the server before the section becomes viewable)
4. 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.

1. From the add-section menu, click either Add Photo/Movie or Add File (a multi-file section can be created from either file picker)
2. In the file picker, select two or more files at once
3. The Edit Section dialog opens with the selected files listed as its content
4. Enter the following information:

1. Optionally add more content:
2. Files: Click the Add button to add more files
3. Web pages: Click the Add Web button and enter a title and URL
4. Edit the Title of each content item as needed
5. Remove unwanted content using the Delete button ()
6. 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.

3.8.2 Supported File Formats

Supported File Formats List

Note: Office format files (Word, Excel, PowerPoint) are automatically converted to PDF.

Drag and Drop

You can also upload files by dragging and dropping them onto the browser screen.

3.8.3 Editing and Removing Sections

Editing a Section

In list view, edit a section from the Edit button () on its row.

1. Click the Edit button () of the section you want to edit
2. The Edit Section dialog appears
3. Modify the information
4. Click the Save button

In grid view there is no edit button on the card; edit from Edit mode instead.

1. Click Edit at the top right to enter Edit mode
2. Select the checkbox of exactly one section
3. Click the Edit button in the toolbar (it is disabled when two or more are selected)
4. Modify the information and click Save. Edit mode and the selection are kept afterwards

Note: When you pick a new cover image for a section, the same 4:3 cropping dialog as for book covers appears (see 3.4 Editing a Book → Cropping the Cover Image (4:3)).

Editing Multi-file Sections

For multi-file sections, you can add/remove files and web pages, and change titles.

1. Click the Edit button of the section
2. The "Edit Section" dialog appears
3. To add content:
4. Files: Click the Add button to select files
5. Web pages: Click the Add Web button and enter a title and URL
6. Click the Delete button () to remove content
7. Edit the title field to change content titles
8. Click the Save button

Headline Actions

In a multi-file section, you can add Headlines to group inner content. A headline is a divider element with a title, description, and color (badge color).

When you hover over a headline row in section edit mode, the following action buttons appear:

Icon	Action	Description
Color badge	Change color	Choose the headline's color (badge color)
Duplicate	Duplicate Headline	Insert a new headline right after the original, copying its title, description, and color
	Delete headline	Delete the headline (content items below the headline are kept)

Tip: Use Duplicate when you want to reuse the same style and color across multiple headlines. Create one headline as a template, then duplicate it and edit the contents.

Removing a Single Section

1. Click the Remove button () of the section you want to remove
2. A confirmation dialog appears
3. Click the Remove button

Removing Multiple Sections at Once

1. Click the Edit button at the top right to enter Edit mode (see 3.8.0 View Mode and Edit Mode)
2. Select the checkboxes of the sections you want to remove
3. Click the Remove button () at the top of the screen
4. Click Remove in the confirmation dialog
5. When finished, click Done to return to View mode

Note: Removing a section also removes the files within that section. This action cannot be undone.

3.8.4 Reordering Sections

You can change the display order of sections.

Reorder by Drag and Drop

1. Drag the section you want to move
2. Drop it at the desired position

Reorder Using the Dialog

1. Click the Reorder button
2. The Reorder dialog appears
3. Change the order of sections using the up/down buttons
4. Click the Save button

3.8.5 Chapter Labels (Section Labels)

A section can carry a chapter label made of a color and an optional name. The label is stored as part of the book, so everyone who can see the book sees the same label (it is not a personal bookmark). It is the same information as "Chapter Labels" in the iOS/Mac and Android apps, and a label set on either side shows up on the other.

How labels are shown

Users with edit permission always see an outlined bookmark icon, even on sections without a label. Users with view-only access see it only on sections that have one.

Adding or changing a label

1. In View mode, click the bookmark icon of the section (or its label strip or name)
2. The "Edit Section Label" dialog appears
3. Turn on the Set Label switch
4. Pick a color under Label Color (blue, red, green, orange, or purple)
5. Enter a name under Custom Label (optional; leave it empty for a color-only label)
6. Click Save

Removing a label

1. Open the Edit Section Label dialog
2. Turn off the Set Label switch
3. Click Save

Note: Only users with edit permission on the book can set or change a label. In Edit mode and Reorder mode labels are shown but cannot be changed.

Listing the chapter labels of every book

The Section Label button in the book list toolbar opens a single list of the chapter labels in every book you can see.

• The color buttons at the top (All plus the five colors) filter the list, and each one shows a count
• Clicking a row opens the section that carries the label
• The Remove (trash) icon at the end of a row removes that one label
• Remove All removes every label in the current filter at once. The confirmation dialog states how many books and how many labels are affected

Note: Removing a label cannot be undone. Labels in view-only books are marked "Read only" and are left untouched.

3.8.6 Exporting Section Files

The files registered in a section can be downloaded exactly as they were uploaded. Unlike .hbx (see 3.9 Importing and Exporting Books (.hbx)), this is not an archive meant for importing: you get the original files, ready to open.

Exporting whole sections

1. Click Edit on the section list to enter Edit mode
2. Select the checkboxes of the sections you want to export (up to 10 at a time)
3. Click the Export button in the toolbar
4. Choose how to receive the files

1. The zip is named {section name}_Files.zip for a single section, or {book name}_Files.zip for several

Exporting selected files inside a section

Files can also be exported individually from the file list of a multi-file section.

1. Click Edit on the file list to enter Edit mode
2. Select the checkboxes of the files you want to export
3. Click the Export button in the toolbar
4. Choose Download as a zip or Download files one by one

Note: When only one file is selected, the original file is downloaded directly without asking.

When exporting is allowed

The conditions are the same as for exporting a book. A book that disallows exporting cannot be exported even by its owner, and a shared book needs both the duplicate and the download permission (see the table in 3.9 Importing and Exporting Books (.hbx)). Sections without files, such as web sections, are not included.
