Controls the possibility to open this popover container by focussing on a connected control.

<b>Note:</b> By default, a type-ahead is only shown to provide suggestions when users enter input in a connected control.
This property enables scenarios where popovers need to be shown earlier (for example, recommendations or recently entered values).
