How to make the elements partially disappear within a frame?

Hey @Jayaseelan ,
Welcome to the community!
To make the elements partially disappear within a frame, here two options:

1. You can crop your picture.
   First, select a layer with an image fill. Then, choose one of the following:

• Click in the toolbar.
• From the Fill section of the right sidebar, click the image thumbnail. Then, open the image mode dropdown and select Crop.

2. Select your layers (image here) and move it to the corner of the frame to make it disappear partially. Please make sure it is still under the frame when you are moving the elements in the blue rectangle)

To better visualise it, you can check the video below:

Hope this helps!
