Properties​
Most Properties have binding options. For more information on Bindings, see Types of Bindings in Perspective. This section only documents the Props Category of properties. The other Categories are described on the Perspective Component Properties page.
| Property | Description | Property Type |
|---|---|---|
| tabs | Responsible for the number of tabs in the container. Adding additional elements to this array will result in an additional tab being rendered on the component. In addition, each element is responsible for determining the content of the tab: either text or an embedded view. By default, the component starts with a single element is this array, set to a value type. Providing a string to the element will set the text on the tab.  If the element is changed to an object data type, then the text on the tab can be set by adding a text value member to the object and providing a string, as seen on element 0 below. Alternatively, viewPath (value data type) and viewParams (object data type) can be added to the element, which allows you to render a view inside the tab as well as pass parameters to it. Element 1 below demonstrates the idea.  New in 8.1.5 A boolean runWhileHidden property can be added to an element that's set to an object data type. This setting determines if contents of this tab loads once the tab is first activated, and if it should persist while in the background when the currentTabIndex changes.  New in 8.1.20 A boolean disabled property can be added to an element that's set to an object data type. This setting determines if a tab can be selected. If the tab is already active when it becomes disabled, users will not be prevented from leaving the tab, but they will not be able to get back to it. The content of the tab is not affected by the enabled/disabled state of the tab. | array |
