Select2 on Dashboards - Default Values

Christian Voß commented on Feb 14

Hi,

I'm using the select2 input on my dashboard and it all works fine, unless I try to declare a default value.

Initially I tried this:

 protected function onInit()
    {
        $this->cssClass("form-control")
        ->multiple(true)
        ->placeHolder("Please select")
        ->value([2]);    
    }

This works fine and it actually set item with the ID=2 as the selected default. However when I then later change the selection and try to get the value from the select on my other dashboard widgets I still only get the default value, even if I had changed it.

$sites = $this->sibling("mySiteSelect")->value();

Result is still = [2], even if I changed the values.

I then reviewed the documentation and found the defaultOption() method. So I tried this:

 protected function onInit()
    {
        $this->cssClass("form-control")
        ->multiple(true)
        ->placeHolder("Please select")
        ->defaultOption([2]);    
    }

Unfortunately, this doesn't select the item with the id=2, although it should according to the documentation. It just adds a new item with the label 2 to the list and doesn't even select it.

I marked this as a bug, as it doesn't do what it says in the documentation.

Can you please either correct it or let me know what I'm doing wrong?

Thanks

Christian

OK, I just found out that it works fine, if I don't set the value into the onInit function. If I set the value into i.e. the dataSource function, then everything works fine.

Thanks for your update. You can also set Dashboard Select2's default value in onCreated method like this:

class MultipleSelect2Demo extends Select2
{
    protected function onCreated()
    {
        $this->defaultValue(array('Australia', 'Austria'));
    }
    ...
}

class SingleSelect2Demo extends Select2
{
    protected function onCreated()
    {
        $this->defaultValue('Australia');
    }
    ...
}
