[BUG] Absolute dragmode does not work on touch devices
Question
Absolute dragmode (with grapesjs touch plugin) does not work on touch devices. GrapesJS version:0.15.8
Expected behavior: The user should be able to move components using drag and drop on touch screens as well.
Current behavior: The user can drag and drop a block just fine. If the user wants to move the dropped component by dragging, it looks like the drag is started(style changed) but the component does not move.
It can be reproduced in the demo as well: https://jsfiddle.net/v9kecdpz/
Steps to reproduce:
- Open the demo (included jsfiddle with grapesjs touch plugin)
- Drag a block into the canvas(or use an existing one)
- Try to move the component by dragging
Tested on: Android Tablet Ipad 2019, IOS 13
Chrome browser was used for testing.
It is most likely not a device/OS specific issue. I am suspecting missing touch events.

This may or may not be related. I noticed with grapejs v0.16.34 on OSX Safari, the event argument inside onStart() function in src/commands/view/ComponentDrag.js is undefined when I drag a block onto the canvas, which can be reproduced with the same fiddle cited above https://jsfiddle.net/v9kecdpz/, again on Safari.
I had to patch it locally as below instead (not the prettiest but it seems to work):
from const { x, y } = Canvas.getMouseRelativeCanvas(event);
to const { x, y } = Canvas.getMouseRelativeCanvas(event || opts.event);
Hey @MartinPutz The asset manager doesn't pop up on the iPad, desktop on touch devices- chrome, firefox, and safari.
And the editor canvas scroll doesn't work on the iPhone.
What am I missing?
Thanks in advance.
Hey @pradeeshattlee
This issue is not really related to the asset manager, but moving the components around, once they are rendered.
I rarely use the asset manager, but as I recall it was working just fine on iPad as well. If I were you I would open a new issue with all the details that might be useful.
