Hi Michael,
Thank you for reaching out!
You can enable the horizontal scrollbar by adjusting the cell width of the Scheduler, as demonstrated below. The reason the scrollbar is not visible in our demo is that the available width does not overflow, as the resource count and width of cell is minimal.
<style> .e-schedule .e-vertical-view .e-date-header-wrap table col, .e-schedule .e-vertical-view .e-content-wrap table col { width: 80px; } </style> |
Sample: Attached as a zip file.

Regards,
Swathi
