i made a app, some times my app hide a ion-navicon, how to always show this icon ? thanks before
pelas any one help me
it is hidden on child-views by default.
And this is good 
, because of usability reasons to have a clear navigation path for your app and the users.
But you can show it always this way:
http://ionicframework.com/docs/api/directive/ionSideMenus/
set the attribute enable-menu-with-back-views to true on your ion-side-menus element.
