Usually, when using ShortPoint to be a container for SharePoint and Office365 Web Parts, the built-in title for the Web Part will no longer be needed, since ShortPoint containers ( such as panels ), can have a better-looking title for your Web Parts, so how can we hide this built-in Web Part title?
You can hide the built-in Web Part title, by following these steps:
Step 1: Edit the Web Part
Click on the down arrow that appears on the right side of the Web Part, then "Edit Web Part" as shown in the next image.
Step 2: Change Web Part properties
After you clicked the Edit Web Part, a Web Part properties panel will appear on the right side of your page,
Expand the "Appearance" toggle item, change "Chrome Type" into "None"
And then Click "OK".
Step 3: Save the page
Once you save the page, you will see that your Web Part will no longer have that built-in title shown.
