An architect or builder can add (or delete) a theme.
To add a theme, click on the edit mode action button from within the grid action bar. You will notice “+” symbols appearing in the top left-hand corner of your grid (within the “Stages/Themes” signpost). Click on the “+” button next to the themes signpost to add a new theme.
The new theme will be added to the bottom of your grid. You can update the theme title by clicking inline on the default heading.
To delete a theme, ensure you are in edit mode: click on the edit mode action button from within the grid action bar to toggle this mode on/off. With edit mode on, you will see the delete action button within each theme heading. Clicking this icon will present you with a “Are you sure?” check (be super careful here as all content in the theme will be deleted). Just click the tick icon to permanently remove the theme from the grid.
