# Tree view

> Group flows by host or process with collapsible tree navigation

Tree view groups captured flows by host or process, making it easier to navigate busy sessions with many different origins.

## Toggle tree view

Press `t` in the flow list to cycle through grouping modes: **flat** → **host** → **process** → **flat**.

In host mode, flows are grouped by hostname. In process mode, flows are grouped by the OS process that initiated them (see [process identification](/features/process-info)).
