How to Trigger the Opening of a Selectpicker Using JavaScript

During the development of my asp.net web app, I encountered a situation where I needed to automatically expand a select picker after a user clicks a button. This select picker is populated from a database and includes a search feature using bootstrap's Selectpicker. Despite trying various codes found online, I could only get it to work with a normal select element.

Is there a specific method to force a select picker to open on a button click?

<select id="MyList01" class="selectpicker show-tick" data-live-search="true"
        data-style="btn-default" runat="server">
javascriptbootstrap-4

Answer №1

selectpicker is a handy tool that transforms a regular select HTML element into a customized one.

<div class="btn-group bootstrap-select open " >
<button ype="button" class="btn dropdown-toggle selectpicker btn-default" 
        data-toggle="dropdown" data-id="MyList01" .... > xxxx</button> ...
 ....
 </div>

In order to trigger an event on this drop down list, you need to target the rendered button and trigger the event using the code below:

$('[data-id="MyList01"]').click();
