Multiselect combobox with ExtJs
- by Justin Johnson
How do you implement a multiselect combobox as part of a Ext.FormPanel using ExtJs? I've been looking, but can't seem to find a solution that is compatible with the latest version of ExtJs (this question is similar, but doesn't have a working/current solution).
This is what I have so far, but it's a single select:
new Ext.FormPanel({
labelAlign: 'top',
frame: true,
width: 800,
items: [{
layout: 'column',
items:[{
columnWidth: 1,
layout: 'form',
items: [{
xtype: 'combo',
fieldLabel: 'Countries',
name: 'c[]',
anchor: '95%',
allowBlank: false,
typeAhead: true,
triggerAction: 'all',
lazyRender: true,
mode: 'local',
store: new Ext.data.ArrayStore({
id: 0,
fields: ['myId', 'displayText'],
data: [
["CA", 'Canada'],
["US", 'United States'],
["JP", 'Japan'],
]
}),
valueField: 'myId',
displayField: 'displayText'
}]
}]
}]
}).render(document.body);
I didn't see any parameters in the documentation that suggests that this is supported. I also found this and this but I could only get them working with Ext 2.
