1) getMultiSelectItems() returns empty list 2) you may need to disable CSP in your application ( https://nightlies.apache.org/wicket/guide/9.x/single.html#_content_security_policy_csp ) 3) disable COOP and/or COEP ( https://nightlies.apache.org/wicket/guide/9.x/single.html#_cross_origin_isolation_with_coop_and_coep ) On Wed, Jun 22, 2022 at 12:34 PM Arunachalam Sibisakkaravarthi < arunacha...@mcruncher.com> wrote: > Hi guys, > We are working to implement bootstrap-select from the Wicket Bootstrap > Extensions project 5.x into Wicket 9.x + Bootstrap 4.x application. > 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.
