Style and the More menu

Style

A handoff chip, not a popover: it opens the right-hand panel's Style tab (Background / Spacing / Typography; the optional canvas_builder_motion submodule adds its own Motion tab alongside it). See Styles for what lives there; the toolbar only shapes the band and its columns.

⋯ More

• Section settings: opens the popover below.
• Add column: appends one more column (up to the configured max), identical to the "+ Column" primary action that otherwise sits on the bar itself once there's room for another column.
• Add section below: inserts a new empty Section immediately after this one.
• Extension items: other modules can register additional chips or menu rows here (documented contract, Events); canvas_builder_ai adds Build with AI this way.
• Disable / Enable section: toggles section_disabled. A disabled section never renders on the front end; in the editor it's still visible, overlaid with a hatched indicator.

Section settings

• Element: the semantic HTML tag the Section band renders as.
• ID / Classes: the section element's id attribute and any extra CSS classes.
• Hide on: per-viewport visibility, independent per breakpoint (no mobile-first cascade; each toggle stands alone). A hidden banner appears in the editor canvas when the active viewport is one you've hidden.

The panel remembers where you were

The prop-group tab you last used (Style, Motion, Review, whichever) is remembered across reloads, so returning to a page does not drop you back on Content every time.

Collapsed toolbar

Clicking minimize shrinks the bar to a small "Section" pill so it stays out of the way while you work on content beneath it; clicking the pill re-expands the full bar. The preference is remembered for the session (not just this one Section) via sessionStorage.
