Hi Vasavi,If I am not wrong there is no component available as of now to get the standard lookup look and feel in your custom components.If you want to add a new button in standard component then - 1. There is already a new button there in every standard lookup 2. If you want to add one more 'New' button for some of the reason then it is not possible. Because its a standard component of Salesforce which is not flexible or configurable enough to add New button in it.If you want to achieve that in that case you need to create a new custom component for a lookup using the SLDS which will be looking similar to the standard one. But again it is a time consuming work.Useful links - Lightning Design System - Look Ups (https://www.lightningdesignsystem.com/components/lookups/⌗react-target)Note - Kindly mark this answer as a best answer if this helped you, so that other's can also get benefit from it.Thanks,
