Tablet and mobile view not resizing
The mobile and tablet devices are pixel pased, so they just resize the canvas to a certain number of pixels regardless of window size. I believe desktop just sets canvas to 100%.

What is the expected behavior?
Mobile and tablet view should resize the canvas when window resizes.
Describe the bug detailed
The desktop view properly resizes the canvas when resizing the window
What is the current behavior?
The canvas does not resize when window resizes below certain width for mobile and tablet view. The panel then covers up the canvas. This does not happen on desktop view, only when you view on mobile and desktop view.
Describe the bug detailed
The desktop view properly resizes the canvas when resizing the window. But only the desktop view. The mobile (including portrait and landscape) and tablet views do not resize

As mentioned by @Ju99ernaut this is how devices work. Honestly, I don't even see the reason behind such a case, why the user should resize the window? You might also start to see/update styles not related to the proper device and that would be definitely confusing.
Thanks for reporting this, @Andrew-Chen-Wang.
The issue with Tablet and mobile view not resizing appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.
What to try:
- Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
// your operation here
}, 0);
-
Check initialization order — make sure components are fully loaded before you interact with them
-
Use the editor's event system — listen to completion events:
editor.on('component:mount', (component) => {
// safe to interact with component here
});
Recommended next steps:
- Test with the latest GrapesJS version if you haven't
- Provide a minimal reproducible example (CodeSandbox) — this helps the team identify the root cause faster
- Include GrapesJS version, browser, and console errors in your report
