We Need to check only sub categories of posts by beaver themer

In This site
we are using beaver themer to show the posts, First we only want to show one parent category here and all sub categories of this same parent category.
We are using code right now.
[wpbb post:terms_list taxonomy=‘category’ html_list=‘yes’ display=‘name’ separator=‘*’ limit=‘5’ linked=‘no’]
Because of this other unwanted catgories are also coming how we can avoid them?
