Some Detailed Examples

In th' plank frontmatter, add a menuPre param t' insert any HTML code before th' menu label. Th' example below uses th' GitHub ay'con.

+++
title = "GitHub repo"
menuPre = "<i class='fab fa-github'></i> "
+++

Order'n Sibl'n Menu/Page Entries

Cap'n Hugo provides a flex'ble way t' handle order fer yer planks.

Th' simplest way be t' set weight parameter t' a number.

+++
title = "My page"
weight = 5
+++

By default, th' Relearrrn theme will use a page’s title attribute fer th' menu item (or linkTitle if defined).

But a page’s title has t' be descriptive on its own while th' menu be a hierarchy. We’ve added th' menuTitle parameter fer that purpose:

For example (for a plank named content/install/linux.md):

+++
title = "Install on Linux"
menuTitle = "Linux"
+++

Ye can change how th' theme expands menu entries on th' side o' th' rrrambl'n wit' th' alwaysopen sett'n on a per plank basis. If alwaysopen=false fer any given entry, its children will not be shown 'n th' menu as long as it be not necessary fer th' sake o' navigat'n.

Th' theme generates th' menu based on th' follow'n rules:

all parent entries o' th' active plank includ'n their sibl'ns be shown regardless o' any sett'ns
immediate children entries o' th' active plank be shown regardless o' any sett'ns
if not overridden, all other first level entries behave like they would have been given alwaysopen=false
if not overridden, all other entries o' levels besides th' first behave like they would have been given alwaysopen=true
all vis'ble entries show their immediate children entries if alwaysopen=true; this proceeds recursively
all remain'n entries be not shown

Ye can see this feature 'n act'n on th' example plank fer children shortcode an' its children planks.

Dis'ble Sect'n Planks

Ye may want t' structure yer planks 'n a hierachical way but don’t want t' generate planks fer those sections? Th' theme got ye covered.

T' stay wit' th' initial example: Suppose ye want level-one appear 'n th' sidebar but don’t want t' generate a plank fer it. So th' entry 'n th' sidebar should not be click'ble but should show an expander.

For this, open content/level-one/_index.md an' add th' follow'n frontmatter

+++
collapsibleMenu = true # this adds th' expander t' th' menu entry if not already set 'n yer hugo.toml
[_build]
  render = "never" # no plank will be generated so th' plank does not have a url
