How to add a control to a Modal control

In the sample there is a button in one of the Modal controls. How was that added?
Also, another modal in the sample has an X in the upper right corner - the other modal control does not. How is an X with closing functionality put into a modal?

Finally, how does one add, say a label, in the original form that holds the two Modal buttons?

Seems containers and floating might be involved. The Modal sample is too simplistic, as well as the documentation, for me to figure these things out.

Thanks for help. Attached is my little demo project. (23.6 KB)

Looks like we need to update the docs for this control - I’ll let you know when this is done.

We’ve updated the docs for Modal (Bootstrap). Hopefully, this answers your questions. Let me know if we need to add more.
