since we are not supposed to provide full solutions here, please show the code you already have tried. the basic idea is to use the onchange-event of the select-element to call a JavaScript-function the open()s a window and passes the desired data to the new open window that you might reference from the opener. you could even use a variable to store a reference to the new window in the window from where you open it.
kind regards

<form id="Mainfrm" name="Mainfrm">

:window.open('newpage.html','m ywin','width=715,height=700');"-->
<option value="" selected>Choose a State</option>
<option value="six">Alabama</option>
<option value="six">Alaska</option>
</select>
</form>
<!-- I want to show is div with the same data in the new window webpage the div id and the option value is the same-->
