Foundation Modal with dropdown：防止关闭模态

Question

大家好，我有一个带有下拉菜单的模式：

Value:<span data-bind="text:value"></span><br>
<a data-bind="click:reveal" > Reveal Modal</a>



    <div data-bind="modal:showModal" class="reveal-modal" data-reveal >
    <a data-dropdown="drop1" aria-controls="drop1" aria-expanded="false">Has Dropdown</a>
<ul id="drop1" class="f-dropdown" data-dropdown-content aria-hidden="true" tabindex="-1">
  <li data-bind="click:duplicate">Double value</li>
  <li data-bind="click:inc">Inc value</li>
</ul>
<p>

而下面的html有如下js:

    ko.bindingHandlers.modal = {
      init: function(element, valueAccessor, allBindings, viewModel, bindingContext) {
        $(document).on('closed.fndtn.reveal', '[data-reveal]', function() {
          if (this === element) {
            valueAccessor()(false);
          }
        });

        var open_binding = allBindings.get('on_modal_open') || null;
        $(document).on('open.fndtn.reveal', '[data-reveal]', function() {
          if (typeof open_binding === 'function') open_binding();
        });
      },
      update: function(element, valueAccessor, allBindings, viewModel, bindingContext) {
        var newVal = valueAccessor()();
        if (newVal) {
          $(element).foundation('reveal', 'open');
        } else {
          $(element).foundation('reveal', 'close');
        }
      }
    };

function Reveal()
{
  var self=this;
  self.showModal=ko.observable(false);

  self.reveal=function()
  {
    self.showModal(true);
  }

  self.value=ko.observable(0);

  self.duplicate=function()
  {
    self.value(2*self.value())
  }

  self.inc=function()
  {
    self.value(self.value()+1)
  }
}

$(document).ready(function()
{
  ko.applyBindings(new Reveal());
  $(document).foundation();  
})

我想要的是当下拉菜单打开时我想关闭它，而不选择任何东西，以防止模式也成为 closed/dismissed。

我该怎么做？

注意：我使用的是 Foundation 5.5.1 版本。
