Examples

Custom Positioning

Control where the tooltip appears relative to the trigger.

<ui:tooltip.root positioning="{placement: 'right'}">
    <ui:tooltip.trigger asChild="{true}">
        <ui:button>Hover for right tooltip</ui:button>
    </ui:tooltip.trigger>
    <ui:tooltip.content>I appear on the right!</ui:tooltip.content>
</ui:tooltip.root>

Open Delay

Set a custom delay before the tooltip opens.

<ui:tooltip.root openDelay="1000">
    <ui:tooltip.trigger asChild="{true}">
        <ui:button>Slow tooltip (1000ms)</ui:button>
    </ui:tooltip.trigger>
    <ui:tooltip.content>I took 1000ms to appear.</ui:tooltip.content>
</ui:tooltip.root>

Close Delay

Set a custom delay before the tooltip closes after the pointer leaves.

<ui:tooltip.root closeDelay="500">
    <ui:tooltip.trigger asChild="{true}">
        <ui:button>Lingers for 500ms</ui:button>
    </ui:tooltip.trigger>
    <ui:tooltip.content>I stay visible for 500ms after you leave.</ui:tooltip.content>
</ui:tooltip.root>

Disabled Interaction

Prevent the tooltip from opening on hover.

<ui:tooltip.root disabled="{true}">
    <ui:tooltip.trigger asChild="{true}">
        <ui:button>No tooltip here</ui:button>
    </ui:tooltip.trigger>
    <ui:tooltip.content>You won't see this.</ui:tooltip.content>
</ui:tooltip.root>

On Icon Buttons

Common pattern for icon-only buttons that need accessible labels.

<ui:tooltip.root>
    <ui:tooltip.trigger asChild="{true}">
        <ui:button variant="ghost" size="icon">
