How to display “Change layout (tool-layout)” features which not display currently?
06:18 20 Jan 2026

Using these following Packages in my package.json:

"cornerstone-core": "^2.2.8",
    "cornerstone-math": "^0.1.7",
    "cornerstone-tools": "^2.4.0",
    "cornerstone-wado-image-loader": "^2.2.3",
    "dicom-parser": "^1.8.3",
    "hammerjs": "^2.0.8",
    "underscore": "^1.13.1"

In my case, I’ve noticed that the DICOM Viewer doesn’t support viewing multiple images simultaneously. Specifically, when you click the “Change layout (tool-layout)” icon (circled in orange in the attached OHIF DICOM Viewer screenshot), its contents don’t appear in the dropdown menu (also highlighted in yellow in the same screenshot), preventing you from changing or selecting a new layout. This isn’t normal.

So, how to fix that problem and make “Change layout (tool-layout)” dropwon work in my DICOM VIEWER like that above OHIF Viewer screenshot ???

How to enable that feature so that when we clique on it it works ??? Because, at this time, it’s unable and does not show its dropdown and features.

Awaiting your answer.
