Customizing the Toolbars for a Framework

      custom toolbars with existing or custom actions.
    - Open the Document Type configuration dialog box for your custom framework and select the Author tab.

          Go to the Toolbar subtab. Figure 1. Configuring the Toolbar   The panel is divided in two sections.

          where you want it added in the right panel section, then click the  Add as child or Add as child or Add as sibling button. Add as sibling button.
Result: When opening a document for the particular framework in Author mode, the toolbar with the new buttons will be displayed in the toolbar area.
Tip: 
    If you have many custom toolbar actions, or want to group actions according to
      their category, add more toolbars with custom names and split the actions to better suit your
      purpose. If your toolbar is not displayed when switching to the Author
      mode, right-click the main toolbar, select Configure Toolbars, and make
      sure the appropriate toolbar (such as the Author Custom Actions
      toolbar) is selected.

  A maximum of 16 toolbars can be added. If you add more, all extra toolbars will be
      automatically converted to sub-toolbars for the last added toolbar.
