Is there a way to get the pop-up date calendar to position itself so it wouldn't get chopped off like in the attached screen shot?

I also noticed the Submit and Reset buttons are centred. Is there a way to get the form centred as well?

Here's how I'm calling the form.

2. <iframe 
3. height='500px' 
4. width='100%' 
5. frameborder='0' 
6. allowTransparency='true' 
7. scrolling='auto' 
8. src='https://creator.zohopublic.com/rleiman/tutorials/form-embed/OM_Orders/sZ4vqFqP4syrKQ22x2JmQrBbQeVORKUqHj6p88VSVxADJNGfhX7gRxe7jqbOsdREQR4QbjgwbsAeaz9hNpZQDZEKazHgwMg774nf'>
9. </iframe>

Maybe there's a tag that aligns it?

Thanks.
