Unsolved Sorting words from SQLite into alphabetical sections

[gabor53]

Hi,
I have the following code which is supposed to list the words from an SQLite db into an alphabetized section list (each section corresponds to one letter of the alphabet):

import Felgo 3.0
import QtQuick 2.9
import QtQuick.Controls 2.5
import QtQuick.Controls.Styles 1.4
import QtQuick.LocalStorage 2.12
import "Database.js" as JS

App {

    AppListView {
        anchors.fill: parent

        // model holds item grouped in sections
        model: ListModel {
            id: listModel
        }

        // add sections as regular list items
        delegate: Item {
            width: parent.width
            height: contentCol.height

            // each list-entry holds the section header + section items
            Column {
                id: contentCol
                width: parent.width

                // header
                SimpleSection {
                    // manually set otherwise induced section title
                    property string section: model.sectionField

                    width: parent.width
                    enabled: true // clickable sections.

                    onSelected: {
                        sectionItems.visible = !sectionItems.visible
                    }
                }

                // items
                Column {
                    id: sectionItems
                    width: parent.width

                    // show all items of section with repeater
                    Repeater {
                        model: listModel
                        delegate: SimpleRow {
                            text: model.wordField
                        }
                    }
                }
            }
        }

        Component.onCompleted: {
            JS.dbGetWordList()
        }
    }
}

Everything works fine except all words appear under each section regardless of their first character:

How can I fix this?
Thank you for your help.
