Dropdown menu list for a table in confluence page for selection

[Subramanian]

While the below piece of HTML code helps in creating drop down list, how to extend this for the new row of records created for a column

<div>
 <select name="Criticality">
 <option value="high">High</option>
 <option value="medium">Medium</option>
 <option value="low">Low</option>

</select>
</div>

 Moreover, the value selected from the dropdown is not getting stored.  When the page is re-opened, the first value in the dropdown is getting displayed for the row.

Confluence does not handle content in HTML.  You should be using macros or apps that can provide drop-downs, not simple html in the body.
