Expand without select

[bogdancalmutchi]

Is it possible to expand a node without also selecting it?
I see in all of the examples from playground and storybook (and in my implementation) that when you expand an item you also select it.

I am using the "click-arrow-to-expand" interaction mode, so there is no click on the actual tree item.

If you just want to expand an item programmatically, there is a expandItem method on the item reference, and also one on the tree environment reference that takes an item id and tree id.

But if you want to completely customize the default behavior for what happens when the user clicks on an item, you can implement an custom interaction mode: https://rct.lukasbach.com/docs/guides/interaction-modes#custom-interaction-modes
Since you are using the click arrow to exapnd interaction mode, you can copy its implementation and adjust it to your needs: https://github.com/lukasbach/react-complex-tree/blob/main/packages/core/src/interactionMode/ClickArrowToExpandInteractionManager.ts

It should probably work to just remove all action.xx calls that do something with selections from there.

Thank you for the reply. Your notes made me dive deeper and i actually went another route for this as i was also using renderItemArrow.
I noticed that the onClick from arrowProps has an actions.selectItem() by default (https://vscode.dev/github/lukasbach/react-complex-tree/blob/main/packages/core/src/treeItem/useTreeItemRenderContext.ts#L187-L188). I just changed that implementation to:

renderItemArrow={({ item, context }) => renderItemIcons( item, { ...context, arrowProps: { ...context.arrowProps, onClick: () => context.toggleExpandedState() } } )}
