From the ExtJS documentation:
flex : Number
This configuration option is to be applied to child items of the container managed by this
layout. Each child item with a flex property will be flexed horizontally according to each
item's relative flex value compared to the sum of all items with a flex
value specified. Any child items that have either a flex = 0 or flex = undefined will not
be 'flexed' (the initial size will not be changed).
But the documentation does not give a lucid application on how it affects the layout and how to use it. Also, I could not find any good tutorials/examples on how to use it on Google.
Appreciate if someone can throw more light on this.
There is a good usage and demo of flex at the following sites:
