 * Hi, in my theme i have vertical menu (works like tree menu)
    The code look like
   this:
 *     ```
       <ul>
         <li>
         <li class="parent opened">
           <ul>
              <li>
              <li>
              <li>
              <li>
              <li class="parent">
                   <ul>
                        <li>
                        <li>
       ```
   
 * When i’am on the deepest li – li with class “parent” only don’t have class opened(
   like this first one)
 * Can’t find and don’t know how to modify my custom walker class. Need help with
   this. I think it does not provide deep levels as i need but maybe i’am wrong.
   Thx for help…
 * My custom walker class is:
 *     ```
       class menu_default_walker extends Walker_Nav_Menu
