A tab bar is a navigational element that lets you switch between different pages of content in the same view. Tab bars in Play are built as a property of the page. You can choose to add the tab bar to some pages and not to others, but the tab bar will be consistent across any pages it is on.
Adding a Tab Bar
In macOS, turn the tab bar on in the attribute panel titled Navigation. Click the pop-up icon to customize all properties.
On iOS, flip the Tab Bar property switch in the Navigation tab of the attribute panels.
Each "item" is a different tab. The Items property includes several sub-properties that customize different parts for each item.
Choose the icon that will display by default when this tab is not selected.
Choose the icon that will display when this tab is selected.
Enter the tab's title using the text field. You can leave this empty if you would like a tab bar with icons only.
The more menu will appear as you hover over an item on macOS. The more menu lets you duplicate and delete an item in addition to editing the object's badge.
To add a badge to any of the icons, select "Edit Badge" and type the desired content (ie. the number of notifications) into the popup. Leaving the text field blank will remove the badge.
Select the page that this tab should navigate to. This link will function as a Go To Page action.
Add a blur or system material to the tab bar's background with the Blur Effect property.
Choose the color of the selected tab's icon and title from your color styles.
Choose the color of the unselected tabs' icons and titles.
Choose the color to tint the tab bar's background.
Choose how the items are spaced within the tab bar. When "Centered" is selected, another property will appear called Item Width which lets you control the space between items.
Adjust the gap between each item's image and title.
