Drag&Drop issue in Kodular Creator Block window

Dear All in kodular blocks problems not drop

Hey @MUBASHIR_KHAN1 This is known issue, just shifting to Firefox browser

Hi, sorry for getting here so late. I can confirm I am able to reproduce this, but still can’t figure why it has started happening “now”…

I’ll try to provide an update as soon as I have one.

Hello Kodular Team and Community,

I am experiencing a persistent issue with the Blocks Editor. I am currently unable to grab, drag, or interact with any blocks in my project.

It seems like there is a lag or a server-side issue preventing the editor from functioning correctly. I have already tried the following:

  • Clearing browser cache and cookies.
  • Trying a different browser (Chrome/Firefox).
  • Checking my internet connection.

Is the server undergoing maintenance, or is this a known bug? Any help would be appreciated as I cannot continue working on my project.

Hi,
I’m sure you haven’t tried Firefox.

It’s known issue and going to resolve soon. read here : Drag&Drop issue in Kodular Creator Block window - #47 by Diego

The fix for this issue has been released and is now available in Kodular Creator as of 2025.10.4.

The problem was caused by a change in Chrome 144  |  Release notes  |  Chrome for Developers (released January 13, 2026) that altered how mouse events behave when page elements are repositioned. This change is part of a Chrome Platform Status and affects all Chromium-based browsers.

The flyout is the panel that opens when you click a block category (like Control, Logic, Math, etc.) in the Blocks editor, showing the available blocks you can drag into your workspace. When you hovered over a block in the flyout, the editor’s code was briefly moving the block in the page structure to bring it to the front. This was harmless before, but with the new Chrome behavior it causes a cascade of extra mouse events, resulting in multiple blocks appearing highlighted and drag-and-drop breaking entirely.

The fix skips that unnecessary repositioning for flyout blocks (since they don’t overlap and don’t need it), while keeping the visual highlight working normally. This has already been deployed, so drag-and-drop from the flyout should now work again in Chrome, Edge, Brave, Opera, and all other Chromium-based browsers.

Hello Kodular Team,

We are currently facing a serious issue in the Kodular Blocks Editor that is completely stopping our app development.

Problem Description

We are unable to add or drag new blocks into the Blocks section. The blocks panel loads, but when we try to add any block to configure app logic, nothing gets added.

Because of this issue:

  • We cannot configure app functionality
  • Existing projects cannot be updated
  • New apps cannot be developed
  • Work is completely blocked on the logic side

This is not a design issue, but a core functionality problem, as the Blocks editor is essential for building any app in Kodular.

What We Have Tried

  • Reloading the project
  • Clearing browser cache
  • Using different browsers
  • Logging out and logging in again

The issue still persists.

Impact

This problem is affecting active projects and causing development delays. Kodular is our primary platform, and issues like this severely impact productivity.

Request

We request the Kodular team to:

  • Investigate this issue urgently
  • Confirm whether this is a platform-wide bug or server-side issue
  • Provide a fix or workaround as soon as possible

Please treat this as high priority, as without the Blocks editor functioning properly, app development is impossible.

Looking forward to a quick response and resolution.

Thank you.

Firefox is currently workaround, also this is latest update about this issue, when did you start experiencing it?
