About how to create component.. please help..!

Hi, guys!

I have work on inventing my portfolio from scratch, and in the meantime, having lost my way…

I need to create a component on a section as you can see throughout the screenshot attached below. The very create component part is inactive…

Is there somebody who is knowledgeable of this ?

I do appreciate with your help in advance!
