Change grouping of store ExtJS

Question

I have the following code:

Ext.define('MyStore', {
    extend: 'Ext.data.Store',
    config: {
        //proxy and domain properties
        model: 'Contact' ,
        autoLoad: true,
        groupField: 'Name'
    }
});

I want to reset the grouping on 'Phone'. How to change grouping of data from store and reload after?

Answer 1

Use the group method of the store. It will clear the previously set groupers.
