Sometimes the visits need to click the plus button to see the sub catgories, i think it not good for user experience.

<script type="text/javascript">
$(function (){
toggleBranch($('ul.tree span.grower'));
});
</script>

You can put those code in your header.tpl of theme folder, and also, can put

toggleBranch($('ul.tree span.grower'));

at end of themes/YOUR THEME NAME/js/tools/treeManagement.js, so it looks like

$('ul.tree.dhtml').removeClass('dhtml');
toggleBranch($('ul.tree span.grower'));
}});
