Jira report plugin, add properties dinamically

Hi everyone,

I am developing a report plugin, there is a file called atlassian-plugin.xml where I have the report properties, more exactly I have only one property, a selector.


        <values class="com.jiraPlugin.utility.GetSprintsForUI"/>


What I need to add here now are some properties related to the selected project, I want to add some textboxes but the number of textboxes depends on the project.
Is there any way to do that?
Thank you
