Details
import "@taprootio/espalier/details";
<esp-details>
A disclosure widget that wraps the native <details> and
<summary> elements. Provides themed styling with a custom
open/close indicator and smooth transitions. Use
esp-details-group to create an
accordion where only one item is open at a time.
Details pick up zone theming from a context attribute on the group
or any ancestor — see the theming guide:
Pre-opened details
Set the open attribute to render the details expanded by
default:
Disabled details
Slots
<esp-details> has a slot:
Default
The default slot holds the content revealed when the details element is opened.
Attributes
<esp-details> has the following attributes:
summary
summary has a default value of "".
The text displayed in the summary row.
open
open has a default value of false.
Whether the details element is open.
disabled
disabled has a default value of false.
Whether the details element is disabled (cannot be toggled).
intent
intent has a default value of undefined.
The element's intent — its meaning: neutral
(no pin), or success, warning, danger, info — each pinned
to its fixed status family (blue for info), retunable per theme
via intents. On token-emitting controls a non-neutral intent pins the
filled-action pair to that family, derived over the governing
zone's theme; class-styled chrome (badges, callouts, status pills)
opts out of inline emission and renders its treatment from CSS
classes instead. An intent never repaints the surrounding zone,
which is what contexts are for. Removing the attribute restores
the element's own default intent.
context
context has a default value of undefined.
A theme-defined color zone. The selected context rebinds designer-facing roles and emits a complete, contrast-enforced semantic token table on this host for descendants to inherit.
Methods
<esp-details> has the following methods:
close
Programmatically close the details element.
traverseToClosest
Traverse up the DOM tree to find the closest element that matches the selector. This method is aware of shadow DOM boundaries and will traverse through them to find the element.
Events
<esp-details> emits the following events:
esp-details-toggle
esp-details-toggle is of type CustomEvent<{ open: boolean }>.
Fired when the details element is opened or closed.
