will take me a while to try this on a mac as I'm on windows...

[kevinlandsberg]

Yeah,

but it seems to get more importance to support Safari cause Apple is selling a lot of computers atm 👍🏿

You can try out Browserstack (https://www.browserstack.com/)

JavaScript Console Error

TypeError: $('.newWidget').draggable is not a function. (In '$('.newWidget').draggable({
      revert: 'invalid',
      scroll: false,
      appendTo: 'body',
      helper: 'clone'
    })', '$('.newWidget').draggable' is undefined)
    ```

@shmolf sounds like you are mixing html5 and jquery-ui there... I don't think that pertains to the site demos but I have not looked on safari yet.

Ack! You're probably right. I'll try changing my assets, and let you know the result.

I was using the following CDN URL
https://cdn.jsdelivr.net/npm/gridstack@3.1.2/dist/gridstack-h5.js

This was referenced by the JS Fiddle example.

Nothing else is loaded, other than CSS.

We may independently use Jquery UI, but not for Gridstack.

Does Gridstack check if Jquery UI is globally available, then references if so?

[adumesny]

please file a separate bug with reproduceable example. And no we don't reference JQ ui if it's available...onlyif our JQ plugin is used.

I have same issue in safari, when i drag a grid element. I'm using latest release build:

[Error] ReferenceError: Can't find variable: DragEvent
initEvent (gridstack-h5.js:2:58075)
_dragStart (gridstack-h5.js:2:41983)
_dragStart

[adumesny]

for now you will need to use the jquery version
