Hi! Sounds like a CSS/display issue.
Did you inspect which css rules apply to the select and its children?

But, the BootstrapMultiSelect shows an empty list without any options. I inspected the rendered html page, it seems everything is ok and has all the options . Java new BootstrapMultiSelect<String>("multiSelectItems", getMultiSelectItems()); HTML <select class="form-control selectpicker" wicket:id="multiSelectItems" multiple="multiple"> </select> Could you help me to identify and fix the problem? Components used in our project: 1. Wicket 9.x 2. Wicket Bootstrap 5.x (Bootstrap 4.x) 3. JQuery 3.6.0 Note: It works as expected in a simple Wicket quickstart project. I couldn't find what went wrong in our app. *Thanks And RegardsSibi.ArunachalammCruncher*
