I am working on an interface that includes a button with a dropdown list. Here is an example:
<a href="https://jsfiddle.net/DTcHh/16589/" rel="nofollow">jsfiddle</a>While the list is scrollable, I am looking to add a fixed button at the bottom. How can I achieve this design?
To achieve the desired layout, place the button after the ul element and limit scrolling to only occur within the 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>
You can control the height of the ul in CSS to see the scroll functionality in action:
ul{
overflow:hidden;
overflow-y:scroll;
height: 100px;
}

Do you need to change an option into a button instead? Decide whether to include it on the list or not
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">Choose
<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>
<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>
<li><a href="#" class="small" data-value="some-option7" tabIndex="-1"><input type=button value="something"></a></li>
</ul>
<a href="#" class="small" data-value="some-option8" tabIndex="-1"><input type=button value="another thing"></a>
