Stop focus on control

Hello

I have created a master detail app which has a list with a datepicker in the bar at the top of the list.

Does anyone know how I can stop the datepicker getting focus when the app is loaded?

The issue is that on an iPad the datepicker pop up is displayed when the app loads, due to the focus.

I can close the pop up programattically after the list has loaded easily enough but I just want to stop the focus on the datepicker, so the user never sees it.

I have tried setting the getFocusDomRef for the datepicker to something else, but this stops the popup working completely.

Any ideas.

Thanks

Andrew
