How to install

How to use

ReactHint Property	Type	Default Value	Description
attribute	String	"data-rh"	Allows to set a custom tooltip attribute instead of a default data-rh.
className	String	"react-hint"	You can completely override a tooltip style by passing a className property.
delay	Number	0	The default delay before showing a tooltip.
events	Boolean	false	Enables/disables mouseOver events. Disabling events is useful in case you want to trigger a tooltip programmatically.
hover	Boolean	false	Enables to hover a mouse cursor over a tooltip.
position	"top", "left", "right", "bottom"	"top"	Allows to customize a default placement of tooltips.
ref	Function		You can get a reference to an instance by passing a function which will set it for you, e.g. <ReactHint ref={(ref) => this.instance = ref} />. This might be needed to programmatically trigger a tooltip by calling this.instance.setState({target}) or update it's content by calling this.instance.forceUpdate().

DOM Element Attribute	Type	Default Value	Description
data-rh	String or #element-id		To show a tooltip on any DOM element and its children add data-rh attribute with a tooltip text to the element. Pass #element-id instead of a text to show the element's HTML content.
data-rh-at	"top", "left", "right", "bottom"	"top"	Allows overriding the default tooltip placement.
