Layer

The layer is responsible for the positioning of an element on a page. For example, you wrap a tooltip with a layer to make its position relative to a target. You can specify up to 12 different positions.

If you use a layer with a component that could be opened or closed, you have to make sure you re-render the layer the first time you open the component, otherwise it will end up with a wrong position.

Installation

npm install ak-layer

Using the component

HTML

This package exports the ak-layer React component.

Import the component in your React app as follows:

import Layer from 'ak-layer';

const myContent = (<div>I'm going to be aligned to the right!</div>);

ReactDOM.render(<Layer position="right middle" content={myContent}>
  <div>Some content</div>
</Layer>, container);

Any content that is passed to Layer as children will always be rendered and any content passed throught the content prop will be rendered aligned to the internal content.

Layer

Kind: global class

• Properties

  • layer.position : String
  • layer.boundariesElement : String
  • layer.autoPosition : Boolean
  • layer.offset : String
  • layer.content : ReactElement

new Layer()

The layer is responsible for the positioning of an element on a page relative to another element.

layer.position : String

Position of a layer relative to its target. The position attribute takes two positional arguments in the format position="edge edge-position", where edge specifies what edge to align the layer to, and edge-position specifies where on that edge the layer should appear. Refer to the table below for examples:

	top left	top center	top right
left top				right top
left middle		target		right middle
left bottom				right bottom
	bottom left	bottom center	bottom right

Kind: instance property of Layer
Default: "right middle"
HTML Example

<Layer position="top left"></Layer>

layer.boundariesElement : String

Element to act as a boundary for the Layer. The Layer will not sit outside this element if it can help it. If, through it's normal positoning, it would end up outside the boundary the layer will flip positions if the autoPosition prop is set.

Valid values are "window" and "viewport" If not set the boundary will be the current viewport.

Kind: instance property of Layer
Default: "viewport"
HTML Example

<Layer autoPosition boundariesElement="window"></Layer>

layer.autoPosition : Boolean

Sets whether a Layer will flip it's position if there is not enough space in the requested position. i.e. if a layer is set to position="top middle" but placing it there would cause it to be outside the viewport (or the boundariesElement if that is set) the Layer will instead be positioned in "bottom middle".

Kind: instance property of Layer
HTML Example

<Layer autoPosition={true}></Layer>

layer.offset : String

A string representing the offsets from the target element in the format "[x-offset] [y-offset]", measured in pixels.

Kind: instance property of Layer
HTML Example

<Layer offset="0 2"></Layer>

layer.content : ReactElement

HTML content to display in the layer. Will be aligned to the target according to the position prop.

Kind: instance property of Layer
HTML Example

const myContent = (<div>Some content</div>);

ReactDOM.render(<Layer position="right middle" content={myContent}>
  <div>I'm the target!</div>
</Layer>, container);
