Lets take our button click and do something more useful with it. For this example, we are going to add a config option to each menu item that will be used to determine what content file to load in the body of our page:
{
xtype: 'tbsplit',
text: 'Help',
menu: [{
text: 'Genre',
helpfile: 'genre',
handler: Movies.showHelp
},{
text: 'Director',
helpfile: 'director',
handler: Movies.showHelp
},{
text: 'Title',
helpfile: 'title',
handler: Movies.showHelp
}]
}
Note the helpfile config option that we have added to each of the menu items config. We have made this config property up so that we have a way to store a variable that is unique to each menu item. This is possible because config properties can be anything we need them to be, and can be created on the fly. In this case, we are using a config property as a variable that holds the name of the file we want to load.
The other new thing...
