FAQ group

would like to check that I have set multiple FAQ group show on the page.
when loading to the page, it is shown as below.

All Top10 General

and it will show All as the default FAQ group.

but as all three groups names are showing the same color with no indicator, so it is difficult to know the current content is under which FAQ group.
may I know how to set an indicator or maybe different color of the selected group name, so we know the FAQ content is shown under which FAQ group?

Thanks.
