JS Date Picker - Display position.

Hi, I have a date picker, I have included all the files attached. Just unzip and click the index files and see it works.
I can change and move the position of the the Appearance of the calendar in the ROME.CSS file.
.rd-container-attachment {
position: absolute;
}

But I want ".rd-container-attachment" to be in a div in the index file, so I can postion the calendar using style =""
