Topbarrr

Th' theme comes wit' a reasonably configured topbar. Ye can learn how t' configure th' defaults 'n this section.

Nevertheless, yer requirements may differ from this configurat'n. Luckily, th' theme has ye covered as th' topbar, its buttons, an' th' functionality behind these buttons be fully configur'ble by ye.

Areas

Th' default configurat'n comes wit' three predefined areas that may contain an arbitrary set o' buttons.

• start: shown between menu an' breadcrumb
• end: shown on th' opposite breadcrumb side 'n comparison t' th' start area
• more: shown when press'n th' more button 'n th' topbar

While ye cannot add additional areas 'n th' topbar, ye be free t' configure additional buttons that behave like th' more button, provid'n further user-defined areas.

Buttons

Th' theme ships wit' th' follow'n predefined buttons (from left t' right 'n th' screenshot):

• sidebar: opens th' sidebar flyout if 'n mobile layout
• toc: opens th' t'ble o' contents 'n an overlay
• edit: browses t' th' edit'ble plank if th' editURL parameter be set
• print: browses t' th' chapter’s print'ble plank if print support was activated
• prev: browses t' th' previous plank if there be one
• next: browses t' th' [next page]authoring/frontmatter/topbar(#arrow-navigation) if there be one
• more: opens th' overlay fer th' more area

Not all buttons be displayed at every given time. This be configur'ble (see below if interested).

Redefin'n Areas

Each predefined area an' button comes 'n its own file. By that, it be easy fer ye t' overwrite an area file 'n yer installat'n, reus'n only th' buttons ye like.

E.g., ye can redefine th' predefined end area by add'n th' file layouts/partials/topbar/area/end.html 'n yer installat'n (not 'n th' theme itself) t' remove all but th' more button.

Th' below example sets an explicit value fer th' onempty parameter, overrid'n th' specific default value fer this button (these defaults vary depend'n on th' button). Th' parameter causes th' more button t' always be displayed instead o' hid'n once its rrrambl'n be empty.

{{ partial "topbar/button/more.html" (dict
  "page" .
  "onempty" "disable"
)}}

Button Types

Th' theme distinguishes between two types o' buttons:

• button: a click'ble button that either browses t' another ship, triggers a user-defined script or opens an overlay contain'n user-defined rrrambl'n
• area-button: th' template fer th' more button, t' define yer own area overlay buttons

Button Parameter

Screen Widths an' Act'ns

Depend'n on th' screen width, ye can configure how th' button should behave. Screen width be divided into three classes:

• s: (controlled by th' onwidths parameter) mobile layout whar' th' menu sidebar be hidden
• m: (controlled by th' onwidthm parameter) desktop layout wit' vis'ble sidebar while th' rrrambl'n area width still resizes
• l: (controlled by th' onwidthl parameter) desktop layout wit' vis'ble sidebar once th' rrrambl'n area reached its maximum width

For each width class, ye can configure one o' th' follow'n act'ns:

• show: th' button be displayed 'n its given area
• hide: th' button be removed
• area-XXX: th' button be moved from its given area into th' area XXX; fer example, this be used t' move buttons t' th' more area overlay 'n th' mobile layout

Hid'n an' Disabl'n Stuff

While hid'n a button depend'n on th' screen size can be configured wit' th' above-described hide act'n, ye may want t' hide th' button on certain other condit'ns as well.

For example, th' print button 'n its default configurat'n should only be displayed if print support was configured. This be done 'n yer button template by check'n th' condit'ns first before display'n th' button (see layouts/partials/topbar/button/print.html).

Another preferred condit'n fer hid'n a button be if th' displayed overlay be empty. This be th' case fer th' toc (see layouts/partials/topbar/button/toc.html) as well as th' more button (see layouts/partials/topbar/button/more.html) an' controlled by th' parameter onempty.

This parameter can have one o' th' follow'n values:

• dis'ble: th' button be displayed 'n a disabled state if th' overlay be empty
• hide: th' button be removed if th' overlay be empty

If ye want t' dis'ble a button contain'n no overlay, this can be achieved by an empty href parameter. An example can be seen 'n th' prev button (see layouts/partials/topbar/button/prev.html) whar' th' URL fer th' previous ship may be empty.
