Fluid Navigationbar height

[crystalsknowledge]

I'm trying to make the height of my navigationbar fluid. I need the navigationbar height to be relative to a wrapping title, but the default styling for the title is absolutely positioned. Any suggestions?

Ext.define('PilotMobileApp.view.view', {
    extend: 'Ext.navigation.View',
    alias: 'widget.view',


    requires: [
        'tMobileApp.view.header',
        'MobileApp.view.phone.aList',
        'MobileApp.view.footer'
    ],


    config: {
        scrollable: true,
        defaultBackButtonText: '',
        navigationBar: {
            backButton: {
                id: 'BackButton',
                width: '3.2em',
                height: '1.65em',
                flex: 1
            },
            cls: 'favBar',
            hidden: true,
            id: 'navBar',
            ui: 'light',
            layout: {
                align: 'start',
                type: 'hbox'
            },
            items: [
                {
                    xtype: 'button',
                    align: 'right',
                    border: 0,
                    cls: 'bookmark',
                    id: 'bookmarkButton',
                    itemId: 'bookmarkButton',
                    margin: '0 0.5em  0  0',
                    style: 'background-image: url("resources/images/star.png");background-size: 18.5px 19px; background-color : transparent;background-repeat: no-repeat;',
                    iconAlign: 'right',
                    text: ''
                }
            ]
        },
        items: [
            {
                xtype: 'header'
            },
            {
                xtype: 'aList',
                minHeight: '5em',
                title: ''
            },
            {
                xtype: 'footer'
            }
        ]
    }


});

docked items need a height to have so by default the navigation bar will get 2.6em height but you can override that by setting the height on the navigation bar.

That's a good point. The title is being absolutely positioned so the bar ignores the height of the title. So once I applied the necessary styling to allow the text to wrap and overflow visible, I retrieve the height of the centered div which contains the title and dynamically apply the height of the centered div to the navigation bar. It seems to work for now. Thanks for you help.
