Hi @artf, After digging deeper into the full stack trace, I found that the error is not in GrapesJS. The event.key.toLowerCase() call is coming from our own application code โ€” a global window.addEventListener("keydown", ...) handler that w...

artf

Hey @saeedhbi, where exactly do you see event.key.toLowerCase() in our code? Are you sure is not coming from your side? Unfortunately, the jsfiddle is not helpful, seems too much AI slopped ๐Ÿ˜…, it's not even loading the editor. Maybe you c...

artf

Thanks @MisterKeyboard for providing the JSON. Your project contains 10K style rules, which is a lot, but still, I'd not expect the load to be impacted that much. @mohamedsalem401 I think we need to verify if data source related changes (e...

@artf Will take a look and give an update on this.

@MisterKeyboard can you share the JSON of the project so we can verify that

Joshmamroud

You were right, it wasn't React or GrapesJS. Event propagation was being stopped by the rc-drawer component I was using. @artf thanks for your help, this has been an issue from day one.

artf

Hey @Joshmamroud we have this code that propagates keydown keyup keypress events to the parent document, this allows keymaps to work, ensure to not contain any code/component which prevents the propagation of those events.

Joshmamroud

Hey @artf, I believe it may be blocked by React. Any suggestions on how to re-bind these event listeners? Not even sure if that is the right solution or path.

createCustomEvent Doesn't Handle Mouse Events Correctly

Version: 0.17.4 / git master Describe the bug detailed FrameView repackages keyboard and mouse events here: https://github.com/artf/grapesjs/blob/07061ae1307fedf2a3b9bd585ce0cb30f653f112/src/canvas/view/FrameView.js#L389-L399 I think the reason is related to redirecting iframe events to parent frame events. This would...

ClaudeCode

Thanks for reporting this, @anlumo. The issue with createCustomEvent Doesn't Handle Mouse Events Correctly appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM mo...

Typo for word "layer" in german language support

In the german locale file there is a typo in line 75 for the word "layer". Instead of layer: 'Evene' it should be layer: 'Ebene' someone must have accidently hit v instead of b on the keyboard when translating it. I am creating a pull request for it right now.

[Bug]: Cannot use 'delete key' on keyboard when editing text.

Hello. I have a problem, that I can edit text, but I cant use the delete key on keyboard. Here is my code: https://pastebin.berkearas.de/?e1c4c8db9a70894f#DCUHVHZzyhFTnAk2RoJ9faQxQPvAqWMoiBqXHMEzRH5G

artf

Thanks for the report, I'll push a new release with the fix

aakos

I have the same problem. Version: 0.15.8 Tested: Chrome 83 Tracked it down to keymaster blocking. Running this would let edited text backspace delete: editor.Keymaps.keymaster.unbind('backspace')); Could be this #2758

BerkeAras

@aakos Thank you. `editor.Keymaps.keymaster.unbind('backspace');editor.Keymaps.keymaster.unbind('delete');` works. But there should be a fix for that problem.

[Help]Keyboard on mobile device will not display on text edit? Anyone else?

Is anyone else having this problem? Or resolved it? Editing on a tablet seems reasonable. While using a mobile device I cannot get the keyboard to display when trying to edit a text field. Even using the grapes touch plugin does not help. There is an example here: http://jsfiddle.net/v9kecdpz/

Is there something else I can do to get a response? I included a demo jsfiddle. Many answered questions don't have an example. So, what am I doing wrong?
