The ToolBar component for React represents a toolbar where different tools (including other components) can be automatically added. By default, the ToolBar supports the following components: Button, ToggleButton, DropDownList, ComboBox and nput. Custom tools can be created and added. The ToolBar can be resized and when there is not enough space to show all tools, they are minimized and appear in the minimize pop-up. The component automatically separates buttons in groups, which are specified by inserting separators ("|") in the tools definition.
