By default the dropdown will automatically close if any of its elements is clicked, you can change this behavior by setting the auto-close option as follows:
always - (Default) automatically closes the dropdown when any of its elements is clicked.
outsideClick - closes the dropdown automatically only when the user clicks any element outside the dropdown.
disabled - disables the auto close. You can then control the open/close status of the dropdown manually, by using is-open. Please notice that the dropdown will still close if the toggle is clicked, the esc key is pressed or another dropdown is open.
Here is a sample : Plunker
<div class="btn-group" dropdown auto-close="disabled">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger dropdown-toggle" dropdown-toggle>
<span class="caret"></span>
<span class="sr-only">Split button!</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
