bootstrap dropdown open on pageload

Question

Ive got this dropdown styled with bootstrap:

Answer 1

The dropdown is toggled with having the additional class 'open' added to the enclosing <li> element. So if you want to have it open on page loading:

<li class="dropdown open">

That will do the trick.

Answer 2

This little bit of jQuery script (I'm assuming you've loaded it becasue you're using Bootstrap) ought to do the trick. Once the DOM has loaded, it sends a click() to the dropdown toggle button.

$(document).ready(function () {
    $("#posuvnik").click();
});

There is probably a way to do it in straight CSS, but without seeing more of your code it's hard to know.
