Hi eveyone I was wondering if you could help me I have an Infobox, see one below link.

but I would like it so it collapses leaving only the word "Relationships" and the colour intact.

I am not sure what I need to add to the template seen below

I have tried various different codes but I do not really have an idea of what I am doing.
