/** * `tagfield` provides a combobox that removes the hassle of dealing with long and unruly select * options. The selected list is visually maintained in the value display area instead of * within the picker itself. Users may easily add or remove `tags` from the * display value area. * * @example * var shows = Ext.create('Ext.data.Store', { * fields: ['id','show'], * data: [ * {id: 0, show: 'Battlestar Galactica'}, * {id: 1, show: 'Doctor Who'}, * {id: 2, show: 'Farscape'}, * {id: 3, show: 'Firefly'}, * {id: 4, show: 'Star Trek'}, * {id: 5, show: 'Star Wars: Christmas Special'} * ] * }); * * Ext.create('Ext.form.Panel', { * renderTo: Ext.getBody(), * title: 'Sci-Fi Television', * height: 200, * width: 500, * items: [{ * xtype: 'tagfield', * fieldLabel: 'Select a Show', * store: shows, * displayField: 'show', * valueField: 'id', * queryMode: 'local', * filterPickList: true * }] * }); * * ### History * * Inspired by the SuperBoxSelect component for ExtJS 3, * which in turn was inspired by the BoxSelect component for ExtJS 2. * * Various contributions and suggestions made by many members of the ExtJS community which can be seen * in the [user extension forum post](http://www.sencha.com/forum/showthread.php?134751-Ext.ux.form.field.BoxSelect). * * By: kvee_iv http://www.sencha.com/forum/member.php?29437-kveeiv */Ext.define('Ext.form.field.Tag', { extend:'Ext.form.field.ComboBox', requires: [ 'Ext.selection.Model', 'Ext.data.Store', 'Ext.data.ChainedStore', 'Ext.view.TagKeyNav' ], xtype: 'tagfield', noWrap: false, /** * @cfg allowOnlyWhitespace * @hide * Currently unsupported since the value of a tagfield is an array of values and shouldn't ever be a string. */ /** * @cfg {String} valueParam * The name of the parameter used to load unknown records into the store.
