This widget belongs to the Basic category in the widget library. It enables you to create a horizontal or vertical tab bar that can contain text or images, point to a HTML page, or call a page from the app or from another app. This is used to display a maximum amount of information in the least number of pages.

Notes

   See General remarks on widgets.

• A Tab widget can only display one type of information, - app pages or other information.
• Each tab title can contain HTML code and/or an image defined in the text editor.

Best Practice

• Define the height of the widget so that all of the tabs are displayed.
• Use the Theme > Set Full Height property to automatically display the maximum height of the tab contents in execute mode.
• If you want to group a small amount of information within sections in a multilevel menu, you should use the Accordion widget.
• To add an image to a tab title, you can use the icons found in the icon gallery provided by EasyVista. You can then apply the same graphic properties to the tab title, i.e. size, font, or color.
