I want to create a TabNavigator, in which some of the tabs
contain a dropdown list. When those tabs are clicked, the
dropdown list is displayed and you can select one of the
items in the list. The display will change after the selection.
Is there is simple way to do it within TabNavigator?
I don't think you want a TabNavigator then. The tabs in a
TabNavigator are used to, on click, switch through a view stack for
Seems like you could do what you wanted without a
TabNavigator at all. Place some labels at the top (styled like tabs
if you so desire), on click use an Effect to show a canvas sized as
your desired subnav (wipe down from the label you clicked, move it
via animation, bounce, etc).
