How to remove the 'Options' to collapse/expand the widget?

[Bird1]

I have cloned the 'Variable Summarizer' widget but I found that the Options to collapse/expand comes (even all the source codes are from the original one). Do anyone know how to remove it?

The original widget 'Variable Summarizer' is working fine. There's no 'Options' to collapse/expand.

Try

c.toggle = true;
c.hide_control = true;
