With reference to my previous post "Replicate Lightning Experience Opportunity Progress Bar into Salesforce Classic UI" , since people are asking for easy way to replicate this, I am going to provide an unmanaged package to help people get this beautiful view at a click away.
Step #1
XperienceProgressBarForSalesforceClassic
Version 1.3
Use this URL to install the package into any organization:
https://login.salesforce.com/packaging/installPackage.apexp?p0=04t90000000NOPH
Note: If you are installing into a sandbox organization you must replace the initial portion of the URL withhttp://test.salesforce.com
Step #2
Click Install button.
Some post-installation steps are identified below to help you get going.
Step #3
After installation, edit your Opportunity page layout to add a one column Section with '.'(a dot) as its name just above detail section as shown in screen shot below.
Step #4
Drag and drop this VF page "Slds_OpportunityProgressBar_Page" inside the added section.
Step #5
Set the VF properties(width= 100%; height=80) by clicking on wrench icon as shown in image below.
Step #6
Save your page layout to get the view as shown in this image.
Quite simple. Isn't it? :)
Note: This is designed exclusively for Opportunity stage field. However it can be tweaked to get it working for other objects as well.
