this code works for me:

root("showcase") {
            width = 100.perc
            stackPanel {
                width = 100.perc
                vPanel(justify = FlexJustify.CENTER, alignItems = FlexAlignItems.CENTER) {
                    val loginPanel: FormPanel<HbsPerson> = formPanel() {
                        add(HbsPerson::name, Text(label = tr("User name:")).apply { placeholder = "" })
                        add(HbsPerson::hometown, Password(label = tr("Password:")).apply { placeholder = "" })

                        add(HPanel(spacing = 10) {
                            button(tr("Login"), "fas fa-lock", ButtonStyle.PRIMARY).onClick {
                            }
                        })
                    }
                }
            }
