Header Side Panel Trigger

The header icon that opens the side panel. Shows only while the Side Panel is switched on in Theme Options. It is shown in the block inserter as Canvas Header Side Panel Trigger and registered as canvas-core/header-side-panel-trigger.

Select the block on a page and its own settings open in the sidebar, in the panels below:

Settings

Each setting is named exactly as the block editor names it, followed by what it does and what it starts as. Where a setting carries a Shown when line, it stays hidden until that condition is met, which is the usual reason a setting looks missing from the sidebar:
