nope, I mean the link (https://github.com/frantic0/sema-next/blob/editors/src/pages/playground/index.svelte) [https://github.com/frantic0/sema-next/blob /editors/src/pages/playground/index.svelte] which you included in the description

I mean, if a value cannot be iterated, then it must be `undefined`. what the columns are equal to, in the debug session ?

https://github.com/vaheqelyan/svelte-grid/blob/master/www/src/routes/examples/add_remove.svx#L34 This is for " X " if you want to delete the widget. This might help you Also can you send me the [repl](https://svelte.dev/repl/hello-world?version=3.35.0) link.

> It solves the issue with component closing, but still the transitioning seems to be somehow broken, which is another issue. Yes I asked you about the repl mostly for...

yes `cols` must be `Array` you basically tell the grid to have 6 columns, when the width of the container is >= N (1200)

I thought it would be nice to have at least one demo version. for example charts or dashboards. (especially it would be interesting to build a dashboard using svelte)

also i have built a small application based on svelte and svelte-grid (v1 old, very old). https://layout-master.now.sh/

It's possible, but it's a little more complicated.I'll show you the code tomorrow.

Try this [repl](https://svelte.dev/repl/3cd7079102534d4da9f82096b83dd6bd?version=3.12.1) I do not why but `bind:items={nestedOne}` crashes my firefox. I also suggest you limit the maximum width and height of elements in nested grids

If I'm not mistaken `bind:items={nestedOne}` does not give problems in an earlier version of svelte
