collapse row pivots on data grid by default

[f0ster]

Is there any way to collapse row pivots on the datagrid viewer by default, on load? Thanks

collapse(n) on a <perspective-viewer>'s .view property will collapse all rows to depth n, just like shift+click on a row. For current perspective. you will need to ensure that

• The perspective-viewer-datagrid plugin is currently loaded - calling collapse or expand on a view with other plugins won't currently work (e.g. D3FC).
• The viewer has already been rendered - since this is a dataset operation, calling it before the data is fully loaded does nothing. You can use await viewer.load(), or use flush() for this.

This is very helpful, thank you 🥳

hello
can this be called on a perspective widget ?
I work in jupyterlab environment and I don't manage to group rows by default - would anyone be able to share a working example?

Thanks for the awesome library !
