如何在WordPress中添加多列引导程序菜单？

Question

我想在WordPress中添加3列引导菜单，但我无法做到这一点。我已经尝试了很多，但子菜单和列不是显示。谁能帮帮我吗。

这是我的引导代码。

<nav class="navbar navbar-default" role="navigation">

  <div class="container">
    <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
          <a class="navbar-brand" href="<?php bloginfo('url')?>">
            <img alt="Brand" src="img/is-logo.png">
