Hi Carlos, The problem is, when it's many level deeper (components in components) some MDL components sizes became unpredictable.
As an example look into this following screenshot. It has three TabBarPanels in their respective components: - First TabBarPanel content has a sky-blue background and it sizes percentWidth=100 properly. - First TabBarPanel also has a sub-NavigationLayoutContent - Second TabBarPanel content has a dark-blue background but it's shown percentWidth NOT 100 at all - Second TabBarPanel also has sub-sub-NavigationLayout-NavigationLayoutContent - Third TabBarPanel has a long ul-li list only - You can see the whole content cropped to a smaller block - It's not setting by 100% width or height <http://apache-flex-development.2333347.n4.nabble.com/file/n59828/Untitled.png> This is a sizing problem. I did used Grid/Card etc. for liquid layout. But it fails. Here's the code file for your test: https://kobra.io/#/e/-KdeMdE5Rt2hmU7PRPp2 Thanks! -- View this message in context: http://apache-flex-development.2333347.n4.nabble.com/FlexJS-MDL-TabBarPanel-children-do-not-gets-flexible-sizes-tp59686p59828.html Sent from the Apache Flex Development mailing list archive at Nabble.com.
