<cf_dbtree
instancename="instance id"

table="table name"
action="get"
type="hovertree"
url_type="param"

Demo

Here's a example to demonstrate how you can expand a menu from a given ID. When clicking on a menu item, the page reloads and expands this item. The active item, the item you have clicked before, will have <li id="instanceName_active"> so you can give it a special style too. E.g.
#instancename #instancename_active a{
color: #228B22;
background-color: #FFFAB5;
}
