Expand/collapse node(s) based on attribute on object in domain model

[mjonsson]

Hi JelteMX,

I'm working on a project where I would need to expand level-by-level or conditionally, based on attributes on node object in the domain model. Optimal solution for gaining full control would be to have a boolean attribute on the node, for example "Expanded" that can be used to expand/collapse nodes individually. Is this possible today? If not, is this something that could be added without too much effort?

Probably not on the node itself. Currently it is not possible.

The reason for this is simple: You don't want to set these values on persistent node objects. A node only holds values that are used for displaying in the table.

That being said, we might be able to build something around a non-persistent view that holds are reference set to selected/expanded nodes. I might have to rethink some of the logic pertaining selections/expansions.

Thanks for the response.

I'm currently loading all information from an external system (Teamcenter). This means all objects in the domain model for the tree table are non-persistent. It would be really nice to have more control on nodes with state attributes like "Expanded" and "Visible". I think it would be beneficial for many applications.

Hare are the functional requirements from customer I do not know how to implement with tree table:

• Being able to expand n-levels in batch, then after n-level expansion continue to selectively expand. - Hide/show nodes in tree table depending on filter selections. - Search in tree table result

Managed to solve hide/show with CSS. Searching solved with recursive microflow and CSS. However, still not able to resolve expanding/collapsing from microflow
