Fixed tnt ToolHeader

Hi,

is it possible to get a fixed ToolHeader (sap.tnt),

so that is does not move when scrolling down?

It looks like this:

<tnt:ToolHeader>

     <ToolbarSpacer/>

     <Button

          icon="sap-icon://refresh"

          press="onRefreshData"

          type="Transparent"

     />

     <ToolbarSeparator/>

     <Button

          text="{i18n>btnTextDeactivateAccounts}"

          icon="sap-icon://delete"

          press="onDeactivateAccounts"

          type="Transparent"

     />

</tnt:ToolHeader>

Thank you in advance.

Daniel
