Короче мне надо изменить код файла ListFilter.js таким образом, чтобы фильтрация происходила не по целому слову в выпадающем списке, а по нескольким буквам. Привожу код файла полностью:
/**
* List filters are able to be preloaded/backed by an Ext.data.Store to load
* their options the first time they are shown. ListFilter utilizes the
* {@link Ext.ux.grid.menu.ListMenu} component.
*
* List filters are also able to create their own list of values from all unique values of
* the specified {@link #dataIndex} field in the store at first time of filter invocation.
*
* Although not shown here, this class accepts all configuration options
* for {@link Ext.ux.grid.menu.ListMenu}.
*
* Example Usage:
*
* var filters = Ext.create('Ext.ux.grid.GridFilters', {
* ...
* filters: [{
* type: 'list',
* dataIndex: 'size',
* phpMode: true,
* // options will be used as data to implicitly creates an ArrayStore
* options: ['extra small', 'small', 'medium', 'large', 'extra large']
* }]
* });
*
*/
Ext.define('Ext.ux.grid.filter.ListFilter', {
extend: 'Ext.ux.grid.filter.Filter',
alias: 'gridfilter.list',
/**
* @cfg {Array} [options]
* `data` to be used to implicitly create a data store
* to back this list when the data source is **local**. If the
* data for the list is remote, use the {@link #store}
* config instead.
*
* If neither store nor {@link #options} is specified, then the choices list is automatically
* populated from all unique values of the specified {@link #dataIndex} field in the store at first
* time of filter invocation.
*
* Each item within the provided array may be in one of the
* following formats:
*
* - **Array** :
*
* options: [
* [11, 'extra small'],
* [18, 'small'],
* [22, 'medium'],
* [35, 'large'],
* [44, 'extra large']
* ]
*
* - **Object** :
*
* labelField: 'name', // override default of 'text'
* options: [
* {id: 11, name:'extra small'},
* {id: 18, name:'small'},
* {id: 22, name:'medium'},
* {id: 35, name:'large'},
* {id: 44, name:'extra large'}
* ]
*
* - **String** :
*
* options: ['extra small', 'small', 'medium', 'large', 'extra large']
