Drop

Position any element in relation to another element.

The Drop component is aim-aware. This means the drop stays open as long as the mouse pointer moves towards the drop. An additional delay ensures that the drop stays open even if the mouse pointer shortly moves in another direction. A drop closes immediately if another menu item is hovered.

Usage

Any content, like a button, can toggle the drop component. Just add the uk-drop attribute to a block element following the toggle.

<button type="button"></button>
<div uk-drop></div>

To group the toggle and the dropdown, just wrap them with a container element and add the .uk-inline class from the Utility component.

<div class="uk-inline">
    <button type="button"></button>
    <div uk-drop></div>
</div>

Note The Drop component has no default styling. In this example, we've used a card from the Card component for visualization.

<div class="uk-inline">
    <button class="uk-button uk-button-default" type="button">Hover, Click</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

Mode

By default, the drop is toggled on hover and on click. Set the mode option to change the toggle behavior.

Mode	Description
`click,hover`	Toggle drop on click and hover.
`click`	Toggle drop on click only.
`hover`	Toggle drop on hover only.

<div uk-drop="mode: click"></div>

<div class="uk-inline">
    <button class="uk-button uk-button-default" type="button">Hover</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="mode: hover">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

<div class="uk-inline">

    <div class="uk-card uk-card-body uk-card-default" uk-drop="mode: click">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

Parent icon

To create a parent icon, just add the uk-drop-parent-icon attribute to a <span> element.

<button type="button">Parent <span uk-drop-parent-icon></span></button>
<div uk-drop="mode: click"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<div class="uk-inline">
    <button class="uk-button uk-button-default" type="button">Parent <span uk-drop-parent-icon></span></button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="mode: click">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

Width and Grid

You can place a grid from the Grid component inside a drop. Just wrap the content with a <div> element and add the uk-grid attribute. If the grid should stack automatically whenever the drop no longer fits its container, just add the .uk-drop-grid class.

<div class="uk-width-large" uk-drop>
    <div class="uk-drop-grid uk-child-width-1-2@m" uk-grid>…</div>
</div>

Use one of the classes from the Width component to adjust the drop's width.

<button class="uk-button uk-button-default" type="button">Hover</button>
<div class="uk-card uk-card-body uk-card-default uk-width-large" uk-drop>
    <div class="uk-drop-grid uk-child-width-1-2@m" uk-grid>

            Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.
        </div>
    </div>
</div>

Position

By default, the drop is positioned below the toggle. To change its position, set the pos option to the uk-drop attribute. The first part of the value refers to the side where the drop is positioned, while the second part defines its alignment to the toggle.

Position	Description
`top-left`	Positions the drop above the toggle and aligns it to the left.
`top-center`	Positions the drop above the toggle and aligns it to the center.
`top-right`	Positions the drop above the toggle and aligns it to the right.
`bottom-left`	Positions the drop below the toggle and aligns it to the left.
`bottom-center`	Positions the drop below the toggle and aligns it to the center.
`bottom-right`	Positions the drop below the toggle and aligns it to the right.
`left-top`	Positions the drop to the left of the toggle and aligns it to the top.
`left-center`	Positions the drop to the left of the toggle and aligns it to the center.
`left-bottom`	Positions the drop to the left of the toggle and aligns it to the bottom.
`right-top`	Positions the drop to the right of the toggle and aligns it to the top.
`right-center`	Positions the drop to the right of the toggle and aligns it to the center.
`right-bottom`	Positions the drop to the right of the toggle and aligns it to the bottom.

<div uk-drop="pos: top-left"></div>

    <button class="uk-button uk-button-default" type="button">Top Right</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: top-right">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

<div class="uk-inline">
    <button class="uk-button uk-button-default" type="button">Bottom Center</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-center">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: right-top">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
</div>

Boundary

By default, the drop automatically changes its positions if it exceeds the viewport or any other parent scrolling ancestor. It will flip its position to the other side to prevent it from covering the toggle and shift its alignment to fit into the viewport. To set a different boundary other than the scrolling ancestor, just add the boundary: SELECTOR option to the uk-drop attribute using a selector for the boundary. To set a boundary on one axis only, use boundary-x: SELECTOR or boundary-y: SELECTOR.

<div class="my-class">
    <button type="button"></button>
    <div uk-drop="boundary: !.my-class"></div>
</div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<div class="boundary uk-panel uk-placeholder uk-height-medium">

    <button class="uk-button uk-button-default uk-float-left" type="button">Bottom Right</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-right; boundary: !.boundary">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

    <button class="uk-button uk-button-default uk-float-right" type="button">Bottom Left</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-left; boundary: !.boundary">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

</div>

Shift and flip

To disable automatic shifting and flipping, add the shift: false or flip: false option to the uk-drop attribute.

<div uk-drop="shift: false; flip: false"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<div class="boundary uk-panel uk-placeholder uk-height-medium">

    <button class="uk-button uk-button-default uk-float-left" type="button">Bottom Right</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-right; boundary: !.boundary; shift: false; flip: false">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

    <button class="uk-button uk-button-default uk-float-right" type="button">Bottom Left</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-left; boundary: !.boundary; shift: false; flip: false">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

</div>

Auto update

By default, the drop repositions on scrolling. To disable dynamic positioning, add auto-update: false option to the uk-drop attribute. The drop will only be positioned once when opened.

<div uk-drop="auto-update: false"></div>

Target

By default, the drop is aligned to its toggle. To position the drop to a different element, just add target: SELECTOR option to the uk-drop attribute. To change just the side where the drop is positioned or the alignment to another element, use target-x: SELECTOR or target-y: SELECTOR.

<div class="my-class">
    <button type="button"></button>
    <div uk-drop="target: !.my-class"></div>
</div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<div class="target uk-panel uk-placeholder uk-height-medium">

    <button class="uk-button uk-button-default uk-float-left" type="button">Bottom Left</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-left; target: !.target">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

    <button class="uk-button uk-button-default uk-float-right" type="button">Bottom Right</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-right; target: !.target">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

</div>

Inset

By default, the drop is positioned outside the toggle. To change the position to the inside, add the inset: true option to the uk-drop attribute. This option should only be used if the target option is also set so the drop doesn't cover its toggle.

<div uk-drop="target: .my-class; inset: true"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<div class="target uk-panel uk-placeholder uk-height-medium">

    <button class="uk-button uk-button-default uk-float-left" type="button">Bottom Left</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-left; target: !.target; inset: true">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

    <button class="uk-button uk-button-default uk-float-right" type="button">Bottom Right</button>
    <div class="uk-card uk-card-body uk-card-default" uk-drop="pos: bottom-right; target: !.target; inset: true">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

</div>

Stretch

To stretch the drop to fill the size of its closest scrolling ancestor, add the stretch: true option to the uk-drop attribute. To only stretch to one axis, use stretch: x or stretch: y. If the boundary option is set, the drop stretches to the defined boundary.

<div uk-drop="stretch: true"></div>

<nav class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-left">

        <ul class="uk-navbar-nav">
            <li>
                <a href>Hover</a>
                <div class="uk-navbar-dropdown" uk-drop="boundary: !.uk-navbar; stretch: x; flip: false">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
            </li>
        </ul>

    </div>
</nav>

Animation

Apply one or more animations to the dropdown by adding the animation: uk-animation-* option with one of the classes from the Animation component. You can also determine the animation's duration. Just add the duration option with a value in milliseconds. Set animate-out: true to also show an animation when closing the drop.

<div uk-drop="animation: uk-animation-slide-top-small; duration: 1000"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<button class="uk-button uk-button-default" type="button">Hover</button>
<div class="uk-card uk-card-body uk-card-default" uk-drop="animation: uk-animation-slide-top-small; animate-out: true">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>

Alternatively, the Drop component has two additional animation types that are not covered by the Animation component. slide-* animations slide the drop and its content from a selected direction, while with the reveal-* animations, the content of the drop stays static and is revealed from a selected direction.

Animation	Description
`slide-top`	Slides the drop from the top.
`slide-bottom`	Slides the drop from the bottom.
`slide-left`	Slides the drop from the left.
`slide-right`	Slides the drop from the right.
`reveal-top`	Reveals the drop from the top.
`reveal-bottom`	Reveals the drop from the bottom.
`reveal-left`	Reveals the drop from the left.
`reveal-right`	Reveals the drop from the right.

<div uk-drop="animation: slide-top; animate-out: true"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

    </div>

</div>

Offset

To define a custom offset between the drop and its toggle, add the offset option with a value in pixels.

<div uk-drop="offset: 80"></div>

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

<button class="uk-button uk-button-default" type="button">Hover</button>
<div class="uk-card uk-card-body uk-card-default" uk-drop="offset: 80">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.</div>
