Removing the border in primeng p-tree component for expansion

Issue

Which is the best way to remove the border in a primeng component during the expansion.

In my view, the below screenshot will just confuse user as there is an treenode with border and a selected treenode with background color.

So I want to get rid of the treenode border while expansion.

Solution

I figured it out to

.ui-treenode-content:focus {
    outline: none;
}
