Examples

Size

Use the size prop to change the size of the button.

<div class="flex flex-col items-start gap-8 sm:flex-row">
    <div class="flex items-start gap-2">
        <twig:Button size="xs" variant="outline">Extra Small</twig:Button>
        <twig:Button size="icon-xs" variant="outline" aria-label="Submit">
            <twig:ux:icon name="lucide:arrow-up-right" />
        </twig:Button>
    </div>
    <div class="flex items-start gap-2">
        <twig:Button size="sm" variant="outline">Small</twig:Button>
        <twig:Button size="icon-sm" variant="outline" aria-label="Submit">
            <twig:ux:icon name="lucide:arrow-up-right" />
        </twig:Button>
    </div>
    <div class="flex items-start gap-2">
        <twig:Button variant="outline">Default</twig:Button>
        <twig:Button size="icon" variant="outline" aria-label="Submit">
            <twig:ux:icon name="lucide:arrow-up-right" />
        </twig:Button>
    </div>
    <div class="flex items-start gap-2">
        <twig:Button size="lg" variant="outline">Large</twig:Button>
        <twig:Button size="icon-lg" variant="outline" aria-label="Submit">
            <twig:ux:icon name="lucide:arrow-up-right" />
        </twig:Button>
    </div>
</div>

Default

<twig:Button>Button</twig:Button>

Outline

<twig:Button variant="outline">Outline</twig:Button>

Secondary

<twig:Button variant="secondary">Secondary</twig:Button>

Ghost

<twig:Button variant="ghost">Ghost</twig:Button>

Destructive

<twig:Button variant="destructive">Destructive</twig:Button>

Link

<twig:Button variant="link">Link</twig:Button>

Icon

<twig:Button variant="outline" size="icon">
    <twig:ux:icon name="lucide:circle-fading-arrow-up" />
</twig:Button>

With Icon

Remember to add the data-icon="inline-start" or data-icon="inline-end" attribute to the icon for the correct spacing.

<twig:Button variant="outline" size="sm">
    <twig:ux:icon name="lucide:git-branch" /> New Branch
</twig:Button>

Rounded

Use the rounded-full class to make the button rounded.

<div class="flex flex-col gap-8">
    <twig:Button variant="outline" size="icon" class="rounded-full">
        <twig:ux:icon name="lucide:arrow-up" />
    </twig:Button>
</div>

Spinner

Render a Spinner component inside the button to show a loading state. Remember to add the data-icon="inline-start" or data-icon="inline-end" attribute to the spinner for the correct spacing.

<div class="flex gap-2">
    <twig:Button variant="outline" disabled>
        <twig:Spinner data-icon="inline-start" />
        Generating
    </twig:Button>
    <twig:Button variant="secondary" disabled>
        Downloading
        <twig:Spinner data-icon="inline-start" />
    </twig:Button>
</div>

As Child

You can use the as prop on Button to make another element look like a button. Here's an example of a link that looks like a button.

<twig:Button as="a" href="/login">Login</twig:Button>

RTL

To enable RTL support, set the dir="rtl" attribute on the root element.

<div class="flex flex-col gap-8">
    <div class="flex flex-wrap items-center gap-2 md:flex-row" dir="rtl">
        <twig:Button variant="outline">زر</twig:Button>
        <twig:Button variant="destructive">حذف</twig:Button>
        <twig:Button variant="outline">
            إرسال
            <twig:ux:icon name="lucide:arrow-right" class="rtl:rotate-180" data-icon="inline-end" />
        </twig:Button>
        <twig:Button variant="outline" size="icon" aria-label="Add">
            <twig:ux:icon name="lucide:plus" />
        </twig:Button>
        <twig:Button variant="secondary" disabled>
            <twig:Spinner data-icon="inline-start" />
            جاري التحميل
        </twig:Button>
    </div>
    <div class="flex flex-wrap items-center gap-2 md:flex-row" dir="rtl">

        <twig:Button variant="outline" size="icon" aria-label="Add">
            <twig:ux:icon name="lucide:plus" />
        </twig:Button>
        <twig:Button variant="secondary" disabled>
            <twig:Spinner data-icon="inline-start" />
