Can we have reserveScrollbarSpace in Tree Grid ?

[vadim_g]

Hi team

can we have a reserveScrollbarSpace config for Tree Grid, that would show the scrollbar by default, otherwise it's ugly to see the shift to left on node expand (see the Gif please)

Hi Vadim,

Looks like wrong layout of component on the page. Scroll should not appear on header level. What will happen when you scroll down? Will it scroll data or the entire grid? Do you see this in our demos? https://bryntum.com/products/grid/examples/sparse-index-tree/

Hey Vadim,

I tried your CodePen and don't see the behavior you mentioned.

Which OS and browser are you using?

Configure your grids with

scrollable : {
    overflowY : 'scroll'
}

Thank you Animal, that worked.
