Does the gantt chart have to fill the entire page?

We’re new to this library, trying to locate a tutorial that shows how to reserve a space at the top of the web page to put our own html controls, etc. thanks

Hello David,
You can add HTML elements above Gantt, it is not necessary to make Gantt fill the whole page.
Here is an example with the button:

I don’t think we need a tutorial about adding HTML elements above Gantt.

thanks, i appreciate the link
