Dropdown Select2 and new or empty value

QuestionsDropdown Select2 and new or empty value
mofel asked 4 years ago

Hello,

Is there any way, with a dropdown field to allow adding new value or leave empty value
(a little bit more as an autocomplete but with the select2 design) ?

Thanks
Mofel

You can have empty value in list by prepending ":;"

$col["editoptions"] = array("value"=>":;".$str);

To allow addition is currently not supported.

Hello Abu,

I'm back on this old question because i still have this problem 🙂

Empty value doesn't seem to work with select2 integration (i tried on your demo code)

$col["editoptions"] = array("value"=>":;".$str);

I have a blank line in normal select but not select2.

Do i make something wrong ?

Thanks
Mofel

For select2, you must specify some placeholder text. e.g. '-'
$col["editoptions"] = array("value"=>":-;".$str);
