Lightning Picklist Path Component

Create your custom path for picklist field in any standard and custom objects. The new lightning picklistpath component in Winter18 helps us to display the picklist field progress similar to the lightning path. The path is rendered as a horizontal bar with one chevron for each picklist item, this component doesn't have key fields or guidance information and doesn't display the mark complete button similar to the lightning path. 

<lightning:picklistPath aura:id="picklistPath" recordId="{!v.recordId}" 
?picklistFieldApiName="status" />
