Is there a recommended library for a jquery tree widget

[Doug Bass]

I'm developing a Connect application for Jira cloud and I have some hierarchical data I want to display on the configuration screen for my application.

Does anyone have a recommendation of a library for a tree widget?

Hello Doug!
A Connect app can be developed in any language. But I suppose that you use React for UI. If so, it makes sense to use atlaskit and the Table Tree element:

Hello @Doug Bass 

Same as what @Alexey Matveev said, Atlaskit is the most appropriate library of UI objects and widgets for Connect apps. The Table Tree object doesn't provide all the fancy tree collapse / expand icons, branch lines or branch icons, but that's because it's designed to give your app a consistent look and feel as all others running on Atlassian products.

Just note, the current version of Atlaskit is for React v16, so a few components might not be perfectly compatible with React v18, but there is apparently an update coming soon.
