You use the same ribbon tabs that you create to control the display of ribbon
panels on the ribbon through a workspace, as those used for ribbon contextual
tab states. Instead of using a workspace to control the display of a ribbon tab,
you assign a ribbon tab to one of the predefined contextual states listed under
the Contextual Tab States node in the Customizations In pane.
Predefined contextual tab states range from selecting an object such as a table
or opening a block in the Block Editor.
To assign a ribbon tab to a contextual tab state
1 Click Manage tab ➤ Customization panel ➤ User Interface.
2 In the Customize User Interface Editor, Customize tab, in the
Customizations In pane, click the plus sign (+) next to Ribbon
to expand it.
3 Click the plus sign (+) next to Tabs to expand it.
4 Click the plus sign (+) next to Contextual Tab States to expand it.
5 Drag a ribbon tab from the Tabs node to a ribbon contextual tab state.
6 Click Apply.
To remove a ribbon tab from a contextual tab state
