The toolbar tag helper allows the developer to place custom Html in some areas of a templated control. Each layout template may have named zones where user may place custom Html. Several toolbar tags may be placed within the control tag helper. Each of them must specify the zone where to place the content. It is possible to add several toolbars referring the same zone. Their content is appended to the already existing content. All controls that support row-types support also toolbars.

Several well known zone names are listed as properties of the LayoutStandardPlaces class. Among them LayoutStandardPlaces.Header and LayoutStandardPlaces.Footer that are supported by the default layout templates of Grids and Forms
