Font change

this is done via css.
if you want to change it globally you can simply define the font for the .collapsomatic class by inserting the following under Dashboard > Settings > Collapse-O-Matic > Custom CSS:

.collapseomatic {
   font-family: "Times New Roman", Times, serif;
}

Of course, you would need to define the desired font-family.

If you wanted to define the font only for certain trigger text, you would need to use the trigclass attribute and define that class like so:

[expand title="trigger text" trigclass="my_class"]hidden content[/expand]

and then define the my_class css:

.my_class {
   font-family: "Times New Roman", Times, serif;
}
