将您的document.ready更改为此

$(document).ready(function() {
    $('.multi2').multiselect({ // this is the second multiselect
        includeSelectAllOption: false,
        nonSelectedText: 'Select Teams',
    });
    $('.multi1').multiselect({ // this is the first multiselect
        includeSelectAllOption: false,
        nonSelectedText: 'Select Teams',
        onChange: function(option, checked, select) { // implement onChange listener
        // clear all selection of the second dropdown - This will be called whenever there's a change in the first multiselect
        // You can think of puting in some additional conditions here.
            $('.multi2').multiselect('clearSelection', false);
        }
    });
});

您还需要将 html 更新为 -

<select id="team0" name="team0[]" class="multi1" multiple="multiple"><!-- first dropdown-->

和

<select id="team1" name="team0[]" class="multi2" multiple="multiple"><!-- second dropdown-->

<iframe width="100%" height="300" src="//jsfiddle.net/yellen/fw32gwd2/embedded/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
