Heres the fix/option

Look at the example at http://forum.lowcarber.org/
Theres a Forum called
New Members & Low-Carbers

Theres 2 SUB FORUMS
Introduce Yourself and Newbies' Questions

heres the steps to get Introduce Yourself show under New Members & Low-Carbers

Say you already have the forum
New Members & Low-Carbers
now:
Step A: In ADMINCP click ADD NEW FORUM
under Add New Forum put the Title "Introduce Yourself " ( used in this example and without quotes )
fill in your description

STEP B: scroll down to where it says PARENT FORUM ( no one ) and use the DROP DOWN bar
to show the list of forums and select New Members & Low-Carbers ( used in this example )

Now scroll to bottom and click SAVE

repeat STEP A and STEP B for additional SUB FORUMS

now you're all set as shown in the example link

What you're looking for is PARENT FORUMS and CHILD display
First Create Soccer Forum
Then follow steps A and B to create forum First Division instead of Introduce Yourself

SAVE

repeat for Premier League
