ZOOM functionality in GANTT UI in WD ABAP not working

Question

Dear Experts
We are using GANTT UI element in webdynpro ABAP application with time
scale.
While we increase or decrease GANTT zoom then time scale is not zooming
accordingly.
We are using below transformation lines to generate XML for TIMESCALE,
        <types class="TIMESCALE">
        <type inherits="Gantt.Ribbon" name="Gantt.Ribbon.Days">
            <size>,25</size>
            <labels format="dd MMMM yyyy" unit="DAY"/>
            <fillColor type="C.Ribbon.Middle"/>
          </type>
          <type inherits="Gantt.Ribbon" name="Gantt.Ribbon.Hours">
            <size>,25</size>
            <labels format="HH" unit="HOUR"/>
            <fillColor type="C.Ribbon.Middle"/>
          </type>
        </types>
          <timeScale>
            <!--          &amp;lt;section&amp;gt;
                    &amp;lt;ribbon type="Gantt.Ribbon.Days"&amp;gt;
                              &amp;lt;fillColor type="C.Ribbon.Light"/&amp;gt;
                         &amp;lt;/ribbon&amp;gt;
                         &amp;lt;ribbon type="Gantt.Ribbon.Hours"/&amp;gt;
                    &amp;lt;/section&amp;gt;-->
            <section>
              <ribbon type="Gantt.Ribbon.Days"/>
              <ribbon type="Gantt.Ribbon.Hours">
                <fillColor type="C.Ribbon.Light"/>
              </ribbon>
            </section>
          </timeScale>
Is there any additional parameter we need to use to make this GANTT ZOOM functionality for time scale.
Appreciate your help in this directon.
Many thanks

Thank you Tom,
I'm actually talking about the standard integrated search help which gets created automatically by the system (you got it right). When I click the arrow next to the select option (Material), it open up a small window with title "Multiple Selections". I can enter multiple values manually here. So far it is good. Now if in this screen I click on the dropdown for column "From", I get a list of Materials to select from. The list has multiple selection capabilities. But when more then one value is selected I get an error message "Select exactly one row of value list to copy". The users are asking if we can give them the capability of selecting more then one row here so that multiple values are populated in the small "Multiple Selections" popup. This way they don't have to type single values separately.
Hope this explains the problem. I don't know how to send screen shots in this post. Thanks much for your response.
