When choosing a keyboard model, the keyboard layout changes.
Numlock mode selection is selected via ComboBox (On / off / leave unchanged)
When you select an indicator display mode, the indicator turns on automatically even for one layout. (Flag / Label / Label of flag)
By default, there is always one layout, and if the user does not need to add other layouts, they will not visit this section either. Thus, there is no need to activate the layout list settings.
To save space, the buttons for deleting and sorting layouts are moved to the header. To prevent accidental deletion of the layout when you click on the delete button, a confirmation dialog appears.
A button for viewing the keyboard layout with this layout appears on the selected layout.
I made the design of this section in accordance with the global shortcuts layout
