Hi Ralph,
Thank for the credentials. I have checked your setup and you don’t have any post at all. Are you referring to actual page? If yes, it should be added as an image element on the builder.
For post, it’s layout is controlled by a template. It is automatic. We can only edit the content inside the builder, which is the main post content.
For pages, we can set templates. Once we choose a template with sidebar, the sidebar content is automatic. We can access it on Appearance > Widgets. Then the main content area is what we can build on the content builder. Usually with page, since we have full control, we don’t utilize the featured image but rather build it all on the builder.
For example, you can set the page to FULLWIDTH OR NO CONTAINER OR WITH CONTAINER. Add your first section. You can either add the image as background to this section and GAP element or add it direct as image element.
Then to achieve the sidebar look, add another section. This time you may set to have 2 columns. 1/3 + 2/3. Large column, build the content you want. Small column is for your sidebar. Add the widget area element to get the sidebar content
There’s no point on using a page template with sidebar if you will set the content width to 100%. It will push your current sidebar at the bottom.
