Aligning text in "Categories" box

[djo]

The sub-categories indent as they should. However, if the title is too long for one line, the second line goes back to the original margin.

 

This is what I have:

 

Main Category

--->Sub-category

--->Sub-category with

longer title

--->Sub-category

 

I would like:

 

Main Category

--->Sub-category

--->Sub-category with

--->longer title

--->Sub-category

 

 

I can't seem to find a solution. I'd rather not make the boxes any bigger. Any input would be appreciated.
