Experiment 12345

Panels provide a way to make extra content available alongside the primary page layout, in a way that is accessible and minimizable.

Panels are always minimizable, either by closing or collapsing. The proper close/collapse icon button displays depending on the whether you set the closable attribute. By default closable is false and the panel collapses down to just an expand icon.

Additionally, nve-panel can be have its side property set to left or right to get the proper collapse/expand icon and animation.

Collapsible Panel with External Trigger is for use with a fixed position when collapsed, otherwise the button may have a flat side and not be on the edge of the page.

Closable Panel with External Trigger

Closable Description true The element displays a close control and the user can dismiss it. false The user cannot close the element and must dismiss it programmatically.

The nve-panel-header sub-component can be slotted into nve-panel to get default border styling, and extra sub slots within the header. In this example nve-panel-header is further slotted with elements for slot="title", slot="subtitle", icon-button with slot="action-icon"
