Automatically open Bootstrap dropdown upon loading the page

Displayed below is my dropdown menu styled using bootstrap:

<li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown" href="#" id="posuvnik">15min <strong class="caret"></strong></a>

    <ul class="dropdown-menu">
        <li> <a href="#" onclick="setPosuvnik(1)">15min</a> </li>
        <li> <a href="#" onclick="setPosuvnik(2)">1hod</a> </li>
    </ul>
</li>

I am looking for a way to automatically expand the dropdown menu upon page load. Does anyone have any suggestions on how to achieve this? Thank you in advance :)

Answer №1

To activate the dropdown, simply include the 'open' class in the <li> tag surrounding it. To ensure it is open when the page loads:

<li class="dropdown open">

That's all you need to do.

Answer №2

To solve this issue, you can use a simple jQuery script (assuming you have already loaded it for Bootstrap). This script triggers a click() event on the dropdown toggle button once the DOM has fully loaded.

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

While there may be a way to achieve the same result with CSS alone, without seeing more of your code it's difficult to determine.
