Corex.Tooltip (Corex v0.1.0-beta.4)

View Source

Phoenix implementation of Zag.js Tooltip.

Examples

Basic

<.tooltip id="my-tooltip">
  <:trigger>Hover me</:trigger>
  <:content>Tooltip content</:content>
</.tooltip>

Multiple triggers (Zag)

One tooltip content, several triggers. Each value must be a stable non-empty string and unique within the component.

<.tooltip id="shared-tip" show_arrow={false}>
  <:trigger value="a">First anchor</:trigger>
  <:trigger value="b">Second anchor</:trigger>
  <:content>Same panel for both triggers</:content>
</.tooltip>

For multi-trigger tooltips whose <:content> should follow the active trigger in LiveView, set on_trigger_value_change to a handle_event/3 name and update assigns used inside <:content> (see the e2e Tooltip · Pattern page).

Without arrow

<.tooltip id="my-tooltip" show_arrow={false}>
  <:trigger>Hover me</:trigger>
  <:content>No arrow</:content>
</.tooltip>

API Control

Use an id on the component for API control.

Client-side

<button phx-click={Corex.Tooltip.set_open("my-tooltip", true)}>
  Open tooltip
</button>

Server-side

def handle_event("open_tooltip", _, socket) do
  {:noreply, Corex.Tooltip.set_open(socket, "my-tooltip", true)}
end

Styling

Target parts with data-scope="tooltip" and data-part:

[data-scope="tooltip"][data-part="trigger"] {}
[data-scope="tooltip"][data-part="positioner"] {}
[data-scope="tooltip"][data-part="content"] {}
[data-scope="tooltip"][data-part="arrow"] {}

Trigger and content have data-state="open" or data-state="closed".

On the root element, optional modifier classes:

  • tooltip--{semantic} — surface and ink (for example tooltip--accent, tooltip--brand)
  • tooltip--size-{sm|md|lg|xl} — max width, padding, and arrow scale
  • tooltip--text-{scale} — content font size only (for example tooltip--text-sm, tooltip--text-xl)
