Using a dropdown menu, I want to display options for candidates that can be chosen. Additionally, I would like an input field to filter these options; so that when text is entered, the dropdown menu adjusts accordingly. Specifically, I am looking to set the width of the dropdown menu equal to the input field width. How can I achieve this adjustment and ensure that the dropdown menu appears when text is inputted into the field?
The HTML code currently in use:
<div class="input-group">
<input type="text" class="form-control" aria-label="...">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
</button>
<ul class="dropdown-menu dropdown-menu-right">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
