Class: Dommy::HTMLSlotElement

Inherits:
HTMLElement show all
Defined in:
lib/dommy/html_elements.rb

Overview

‘<slot>` — composes light DOM into the shadow tree. Light DOM children of the shadow’s host get assigned to slots: those whose ‘slot=name` attribute matches a named slot, or those without a `slot` attribute go to the unnamed default slot. If nothing is assigned, the slot’s own children render as fallback content.

#assign(*nodes) ⇒ Object

‘slot.assign(…)` — manual assignment (honored only when the owning shadow uses `slotAssignment: “manual”`). We accept the call and fire `slotchange` in both modes; named mode simply ignores the override.

‘slot.assignedNodes({ flatten: true|false })` — returns the light DOM children currently composed into this slot. With `flatten: true` and no assigned nodes, falls back to the slot’s own children (the default content).
