I am new to jmeter. I successfully installed jmeter into my windows machine. I opened "jmeter.bat" under apache-jmeter-4.0\bin. But the jmeter window is not showing the workbench section in the left panel. I have attached the screenshot below in the ApacheJmeter.
It's not a bug but a feature since JMeter 4:
Workbench has been dropped from UI, you can now use Non Test Elements as immediate children of Test Plan.
You can now use elements in Test Plan as you used previously in Workbench
You can see also an old question that asked why workbench is shown in the first place
You can find all features of Workbench here:
Navigate to Test Plan -> Add --> Non-test Elements, now you could see all required features of Workbench
