wa_tree: Create a 'wa-tree' component

Create a wa-tree component

Description

Generated wrapper for the Web Awesome wa-tree component. When used as a Shiny input, ⁠input$<input_id>⁠ reflects the component's current semantic selectedItemIds state. The Shiny value is returned as a character vector. For stable Shiny selection values, selectable descendant wa-tree-item elements should have DOM id attributes. Generated from Web Awesome metadata.

Usage

wa_tree(
  input_id,
  ...,
  class = NULL,
  style = NULL,
  dir = NULL,
  lang = NULL,
  selection = NULL,
  collapse_icon = NULL,
  expand_icon = NULL
)

Arguments

...	Child content for the component's default slot.
class	Optional CSS class string.
style	Optional inline CSS style string.
dir	String. Optional Web Awesome attribute.
lang	String. Optional Web Awesome attribute.

collapse_icon	The icon to show when the tree item is collapsed. Works best with ⁠<wa-icon>⁠.
expand_icon	The icon to show when the tree item is expanded. Works best with ⁠<wa-icon>⁠.
