I try to use ComboBox on FormPanel, it is defined like this:
{
xtype: 'combo',
name: 'Reasons',
store: new Ext.data.ArrayStore({
id: 0,
fields: ['myId', 'displayText'],
data: [
[1, 'Reason 1'],
[2, 'Second Reason'],
[3, 'Something else']
]
}),
typeAhead: false,
mode: 'local',
valueField: 'myId',
displayField: 'displayText',
allowBlank: false,
editable: false,
forceSelection: true
}
I would like to act like a ordinary select element, when I have editable as false I not able to re-select anymore, when as true ( default ) I need to remove selection ( by backspace or delete ) in order to re-select.
What else I should turn off in order to downgrade combobox to select or shpuld I consider to use other component instead ?
My concern is if I really need ordinary select (not quite ordinary - ability to have store and manipulate options is very cool) - combo
seems to me next level element what got too many features which I need to turn off and combo
is rendered as input with arrow down image what trigger all action.
My question is:
Is it ExtJS element what is using HTML select tag, acting as select, rendering as select ?
The trick is to use triggerAction: 'all'
- it forces the combo dropdown to show all items when you click the down-arrow icon (trigger).
That's probably the most counter-intuitive config option of ExtJS. And it's impossible to figure out what it really does by reading the docs. And like you say, to get a simple combo, you have to specify a myriad of config options, just to turn the fancy stuff off.
The ExtJS guys have promised to fix this in ExtJS 4, but until then I suggest you create your own ComboBox class that's configured the way most often needed in your app. For example I have something like this in my current project:
/**
* Simple combo, that just allows to choose from a list of values.
*/
var StaticComboBox = Ext.extend(Ext.form.ComboBox, {
mode: 'local',
triggerAction: 'all',
editable: false,
valueField: 'value',
displayField: 'label',
/**
* @cfg {[[String]]} data
* Items in combobox as array of value-label pairs.
*/
data: [],
initComponent: function() {
this.store = new Ext.data.ArrayStore({
fields: ['value', 'label'],
data: this.data
});
StaticComboBox.superclass.initComponent.call(this);
}
});
Having that, I can create a simple combo with just a few lines:
new StaticComboBox({
name: 'Reasons',
data: [
[1, 'Reason 1'],
[2, 'Second Reason'],
[3, 'Something else']
]
});
