Toolbars can be used to control action view rendering on mobile devices.
On mobile devices, actions render usually as default action views, that display implicitly in dedicated panes on the screen. When displaying forms on a mobile front-end, you can use a toolbar to control the rendering of the actions.
On Android devices, a TOOLBAR can be used to define the action views that appear in the Android action bar. Toolbar action views are listed first and ordered as they are defined in the TOOLBAR section, followed by the default action views for remaining actions that are not part of the TOOLBAR definition.
On iOS devices, a TOOLBAR renders as the iOS toolbar panel. This toolbar appears at the bottom of the screen, displaying a icon or text for each toolbar item. If there is not enough space to render all toobar items, a three-dot overflow icon appears on the right, to show up the remaining toolbar items.
The iosSeparatorStretch toolbar style attribute can be used to stretch the separators to give more space between action buttons.
