按下ul
之后的按钮,只滚动ul
:
<div class="dropdown-menu">
<ul>
<li><a href="#" class="small" data-value="option1" tabIndex="-1"><input type="checkbox"/> Option 1</a></li>
<li><a href="#" class="small" data-value="option2" tabIndex="-1"><input type="checkbox"/> Option 2</a></li>
<li><a href="#" class="small" data-value="option3" tabIndex="-1"><input type="checkbox"/> Option 3</a></li>
<li><a href="#" class="small" data-value="option4" tabIndex="-1"><input type="checkbox"/> Option 4</a></li>
<li><a href="#" class="small" data-value="option5" tabIndex="-1"><input type="checkbox"/> Option 5</a></li>
<li><a href="#" class="small" data-value="option6" tabIndex="-1"><input type="checkbox"/> Option 6</a></li>
</ul>
<button>btn</button>
</div>
如果您在CSS中设置较小的ul,则可以看到它:
ul{
overflow:hidden;
overflow-y:scroll;
height: 100px;
}

您是否尝试添加选项但应该是按钮? 把它放在清单上还是没有
var options = [];
$( '.dropdown-menu a' ).on( 'click', function( event ) {
var $target = $( event.currentTarget ),
val = $target.attr( 'data-value' ),
$inp = $target.find( 'input' ),
idx;
if ( ( idx = options.indexOf( val ) ) > -1 ) {
options.splice( idx, 1 );
setTimeout( function() { $inp.prop( 'checked', false ) }, 0);
} else {
options.push( val );
setTimeout( function() { $inp.prop( 'checked', true ) }, 0);
}
$( event.target ).blur();
console.log( options );
return false;
});
ul{
overflow:hidden;
overflow-y:scroll;
height: 150px;
}
<div class="container">
<div class="row">
<div class="col-lg-12">
<div class="button-group">
<button type="button" class="btn btn-default btn-sm dropdown-toggle" data-toggle="dropdown">Select
<i class="caret"></i>
</button>
<div class="dropdown-menu">
<ul>
<li><a href="#" class="small" data-value="option1" tabIndex="-1"><input type="checkbox"/> Option 1</a></li>
