# Separators (JavaScript Scheduler) | DayPilot Pro for JavaScript Demo

> [Separators](https://doc.daypilot.org/scheduler/separators/) mark a date/time across the schedule or within a specific resource row. The gray line is global; colored lines belong to individual rooms or floors. Collapse a floor or add overlapping bookings to see the lines follow their rows.
