The panel is a container for grouping and displaying information. It can be collapsed to save space on the screen.
Use the panel if:
- You need to group or display information.
- You want to give users the option of hiding this information.
- You want to show additional information on demand (for example, a panel could show optional input fields for an advanced search).
- The panel control is a container for controls.
- The panel can have a solid or semi-transparent background.
- The panel always includes a header.
- An info toolbar can be added to the panel to show extra information.
A panel consists of a title bar with a header text or header toolbar, an info toolbar (optional), and a content area.
The title inside the title bar can be added by using the “headerText” property. If you use the “headerToolbar” aggregation, the “headerText” property is ignored. With the “headerToolbar” aggregation, you can add a toolbar with any toolbar content inside the title bar. For example, if you need a title text on the left and some action buttons on the right, add a title to the toolbar’s content aggregation, toolbar spacer, and then your buttons.
- When the panel is expandable, an arrow icon (pointing to the right) appears in front of the header. Click or tap this icon to expand the panel.
- When the animation is activated, expand/collapse uses a smooth animation to open or close the content area.
- When the panel expands, the arrow icon rotates 90 degrees clockwise.
- When the panel collapses, the arrow icon rotates 90 degrees counterclockwise.
- The buttons in the header can be clicked/tapped separately.
Overflow Scrolling (Content Area)
- By setting the height to use the default property “auto”, the height of the content area will automatically be adjusted to match the height of its content.
- When the height of the panel is set to a fixed size, the content area can be scrolled through.
