Opening and closing drawers declaratively#

You can open and close drawers with JavaScript by toggling the open attribute, but you can also do it declaratively. Add the data-drawer="open id" to any button on the page, where id is the id of the dialog you want to open.

<pc-drawer label="Drawer" id="drawer-open-declarative">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button data-drawer="open drawer-open-declarative">
    Open drawer
</pc-button>

Code

Edit

Similarly, you can add data-drawer="close" to a button inside of the drawer to tell it to close it.

<pc-drawer label="Drawer" id="drawer-dismiss-declarative">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button data-drawer="open drawer-dismiss-declarative">
    Open drawer
</pc-button>

Code

Slide in from start#

By default, drawers slide in from the end. To make the drawer slide in from the start, set the placement attribute to start.

<pc-drawer label="Drawer" placement="start" class="drawer-placement-start">
    This drawer slides in from the start.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-placement-start");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Edit

Slide in from top#

To make the drawer slide in from the top, set the placement attribute to top.

<pc-drawer label="Drawer" placement="top" class="drawer-placement-top">
    This drawer slides in from the top.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-placement-top");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Edit

Slide in from bottom#

To make the drawer slide in from the bottom, set the placement attribute to bottom.

<pc-drawer label="Drawer" placement="bottom" class="drawer-placement-bottom">
    This drawer slides in from the bottom.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-placement-bottom");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Edit

Custom size#

Use the --size custom property to set the drawer’s size. This will be applied to the drawer’s width or height depending on its placement.

<pc-drawer label="Drawer" class="drawer-custom-size">
    This drawer is always 50 % of the viewport.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-custom-size");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

<style>
    .drawer-custom-size {
        --size: 50vw;
    }
</style>

Code

Edit

Scrolling#

By design, a drawer’s height will never exceed that of the viewport. As such, drawers will not scroll with the page to ensure the header and footer are always accessible to the user.

<pc-drawer label="Drawer" class="drawer-scrolling">
    <div
        style="
            padding: var(--pc-spacing-l);
            block-size: 150dvh;
            border: var(--pc-border-width-m) dashed
                var(--pc-color-neutral-border-normal);
            border-radius: var(--pc-border-radius-l);
        "
    >
        <p>Scroll down and give it a try! ⬇️</p>
    </div>

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-scrolling");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Header actions#

The header shows a functional close button by default. You can use the header-actions slot to add additional icon buttons if needed.

<pc-drawer label="Drawer" class="drawer-header-actions">
    <pc-button
        class="new-window"
        size="small"
        variant="plain"
        slot="header-actions"
    >
        <pc-icon
            library="default"
            icon-style="solid"
            name="arrow-up-right-from-square"
        ></pc-icon>
    </pc-button>

    Lorem ipsum dolor sit amet, consectetur adipiscing elit.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-header-actions");
    const openButton = drawer.nextElementSibling;
    const closeButton = drawer.querySelector('pc-button[slot="footer"]');
    const newWindowButton = drawer.querySelector(".new-window-button");

    openButton.addEventListener("click", () => (drawer.open = true));
    newWindowButton.addEventListener("click", () => window.open(location.href));
</script>

Prevent light dismissal#

If you want to prevent the drawer from closing if the user clicks on the overlay, add the no-light-dismiss attribute.

<pc-drawer label="Drawer" class="drawer-no-light-dismiss" no-light-dismiss>
    This drawer will not close when you click on the overlay.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-no-light-dismiss");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Edit

Prevent drawer from closing#

By default, drawers will close when the user clicks the close button, clicks the overlay or presses the Esc key. In most cases, the default behaviour is the best behaviour in terms of UX. However, there are situations where this may be undesirable, such as when data loss will occur.

To keep the drawer open in such cases, you can cancel the pc-hide event. When cancelled, the drawer will remain open and pulse briefly to draw the user’s attention to it.

You can use event.detail.source to check what triggered the close request. In this example, the drawer will only close when a custom close button inside the footer is clicked. Clicking the overlay, pressing Esc or using the built‐in header close button will all be prevented.

<pc-drawer label="Drawer" class="drawer-deny-close">
    This drawer will only close if you click on the button below.

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-deny-close");
    const openButton = drawer.nextElementSibling;
    const closeButton = drawer.querySelector('pc-button[slot="footer"]');

    drawer.addEventListener("pc-hide", (event) => {
        if (event.detail.source !== closeButton) {
            event.preventDefault();
        }
    });

    openButton.addEventListener("click", () => (drawer.open = true));
</script>

Code

Edit

Customise initial focus#

By default, the drawer’s panel will gain focus when opened. This allows a subsequent tab press to focus on the first tabbable element in the drawer. If you want a different element to have focus, add the autofocus attribute to it as shown below.

<pc-drawer label="Drawer" class="drawer-focus">
    <pc-input
        placeholder="I will have focus when the drawer is opened"
        aria-label="I will have focus when the drawer is opened"
        autofocus
    ></pc-input>

    <pc-button variant="plain" slot="footer" data-drawer="close">
        Close
    </pc-button>
</pc-drawer>

<pc-button>Open drawer</pc-button>

<script>
    const drawer = document.querySelector(".drawer-focus");
    const openButton = drawer.nextElementSibling;

    openButton.addEventListener("click", () => (drawer.open = true));
</script>
