Introduction

Umo Editor Mobile is built on Tiptap and supports adjusting capability boundaries through built-in extensions, custom extensions, and extension disabling.

Compared with Umo Editor and Umo Editor Next, the mobile extension system still follows the same Tiptap-based approach, but the final exposed UI and interaction entry points are more oriented toward touch-first scenarios.

Currently Supported Extension Patterns

Use Built-in Extensions

Mobile includes a large number of commonly used built-in extensions, including but not limited to:

• lists, task lists, indentation, alignment, line height, and letter spacing
• images, audio, video, files, and links
• tables, page breaks, table of contents, footnotes, text boxes, tags, and mentions
• callouts, columns, code blocks, web embedding, and ECharts
• utility-style extensions such as SearchReplace, OfficePaste, Selection, and NodeSelect

For the full list, see Built-in Extensions.

Disable Built-in Extensions

Built-in extensions can be disabled through disableExtensions.

const options = {
  disableExtensions: ['toc', 'mention', 'tag'],
}

Append Custom Extensions

You can append business-specific custom extensions through extensions.

const options = {
  extensions: [myExtension],
}

For more approaches, see Custom Extensions.

Key Differences from Desktop

• Different extension entry points Different on Mobile: even if the underlying extension has the same name, mobile may trigger it through the bottom toolbar, navigation actions, or popup panels rather than the desktop toolbar.
• Not all desktop extension capabilities are fully exposed Partially Unsupported: some desktop productivity features may remain compatible at the data level, but their mobile UI and documentation entry points may not be fully available yet.
• Mobile relies more heavily on the two mechanisms of “disable” + “append” to trim capability boundaries. Mobile-Only

UI Notes

• If you only need extension capabilities, focus on extensions and disableExtensions.
• If deeper capability integration is required, it is recommended to also reference the src/extensions directory in the mobile source code.
