WPF Listbox Wrapping

I have a listbox in which I use a ListBox.ItemsPanel - WrapPanel.

<ListBox ItemsSource="{Binding Path=Applets}" Margin="10,92,10,10" ScrollViewer.HorizontalScrollBarVisibility="Disabled" >
        
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                
                <WrapPanel Orientation="Vertical" IsItemsHost="True">
                    
                </WrapPanel>
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
        
        
        
        <ListBox.ItemTemplate>...

I am trying to have the wrappanel have a behavior such that the items fill in to the right as the width is made wider and wrap as needed when the window is made narrower. I have played with it but the correct combination eludes me. Does anyone have a suggestion?

My next goal would be able to reorder/ sort the items and have the render update.

    The code you have is almost correct, just change the Orientation to Horizontal and it should work as you describe

    You don't have to do anything special for that, it's the normal behavior of a ListBox. Just change the sort order (using ICollectionView.SortDescriptions), and the UI will reflect the changes
