If a content area is configured with many custom buttons with the Button Location attribute set to MainToolbar , it is possible that the buttons do not fit in the toolbar if they have long captions. In this case, the toolbar will be truncated and some of the buttons as well as the 3-dots menu will not be displayed on the screen. To resolve this issue, it is recommended that no more than three buttons have the Button Location attribute set to MainToolbar and that the rest are set to MoreGroup, which will put them in the 3-dots menu.
