Filters / Subcategories — Nested people search filters with subcategories

Nested filters for a people search, shown as three panels. Engagement opens into Sequence, Playbook and Last Activity, and Email opens one level further into Sent, Opened, Clicked, Replied and a list of templates. A blue rule down the left edge shows which group you’re inside.

The middle panel opens one filter fully: a company name, URL or ticker field, a current-company selector, advanced conditions (is not any of, is known, is unknown) and a Boolean operators field with a tutorial link. On the right, applied filters show a count on each group and field, with an × to clear them. Sid turned it into code.
