The Sidecar is a secondary viewing panel that appears to the right of your main workspace content. It allows you to view a reference document or page alongside your primary view. Workspace with sidecar open showing a reference PDF page next to the main document view

​
Opening the Sidecar

Toggle the sidecar panel using Cmd + Shift + O (Mac) or Ctrl + Shift + O (Windows/Linux). The sidecar can display:
  • A specific page from the current document
  • A related or referenced document
  • A secondary view of the same document at a different location

​
Use Cases

​
Side-by-Side Review

Open a data form in the center view and the source document in the sidecar to review extracted values against the original content. Data form in center with source PDF in sidecar for side-by-side review

​
Cross-Reference

When reviewing multi-page documents, use the sidecar to keep a reference page visible while working through other pages in the main view. Main view on one page with sidecar showing a reference page from the same document

​
Detaching to a Separate Window

The sidecar can be detached into its own browser window, giving you a full document viewer on a second monitor or alongside other applications.

​
How to Detach

Click the detach button in the sidecar header, or use the pop-out button in the spatial viewer toolbar. The sidecar opens in a new browser tab as a full document viewer. When the sidecar is detached:
  • The inline sidecar panel collapses to save workspace real estate
  • The external tab shows a full document viewer with all spatial navigation tools
  • Document views, page navigation, and annotation events are synchronized between the main workspace and the detached tab
  • Clicking an attribute or tag in the main workspace focuses the corresponding location in the detached viewer

​
Automatic Reconnection

The main workspace monitors the detached tab with a heartbeat signal. If you close the external tab, the inline sidecar automatically restores after a few seconds. You can also click the collapsed sidecar indicator to re-expand it inline.
If your browser blocks the popup, check your browser’s popup blocker settings and allow popups for the Kodexa domain.
The sidecar is especially useful for documents where data on one page references information on another, such as invoices with terms on a separate page. Detaching to a second monitor makes this workflow even more efficient.
